Description
FIELD OF THE INVENTION

The present invention relates to compounds that inhibit myeloid cell leukemia 1 protein (Mcl-1, also abbreviated as MCL-1 or MCL1); methods of treating diseases or conditions, such as cancer, using the compounds; and pharmaceutical compositions containing the compounds.

BACKGROUND OF THE INVENTION

One common characteristic of human cancer is overexpression of Mcl-1. Mcl-1 overexpression prevents cancer cells from undergoing programmed cell death (apoptosis), allowing the cells to survive despite widespread genetic damage.

Mcl-1 is a member of the Bcl-2 family of proteins. The Bcl-2 family includes pro-apoptotic members (such as BAX and BAK) which, upon activation, form a homo-oligomer in the outer mitochondrial membrane that leads to pore formation and the escape of mitochondrial contents, a step in triggering apoptosis. Antiapoptotic members of the Bcl-2 family (such as Bcl-2, Bcl-XL, and Mcl-1) block the activity of BAX and BAK. Other proteins (such as BID, BIM, BIK, and BAD) exhibit additional regulatory functions.

Research has shown that Mcl-1 inhibitors can be useful for the treatment of cancers. MCl-1 is overexpressed in numerous cancers. See Beroukhim et al. (2010) Nature 463, 899-90. Cancer cells containing amplifications surrounding the Mcl-1 and Bcl-2-1-1 anti-apoptotic genes depend on the expression of these genes for survival. Beroukhim et al. Mcl-1 is a relevant target for the re-initiation of apoptosis in numerous cancer cells. See G. Lessene, P. Czabotar and P. Colman, Nat. Rev. Drug. Discov., 2008, 7, 989-1000; C. Akgul Cell. Mol. Life Sci. Vol. 66, 2009; and Arthur M. Mandelin II, Richard M. Pope, Expert Opin. Ther. Targets (2007) 11(3):363-373.

New compositions and methods for preparing and formulating Mcl-1 inhibitors would be useful.

DETAILED DESCRIPTION

The symbol “—” represents a covalent bond and can also be used in a radical group to indicate the point of attachment to another group. In chemical structures, the symbol — is commonly used to represent a methyl group in a molecule.

As used herein, chemical structures which contain one or more stereocenters depicted with dashed and bold bonds (i.e., and ) are meant to indicate absolute stereochemistry of the stereocenter(s) present in the chemical structure. As used herein, bonds symbolized by a simple line do not indicate a stereo-preference. Unless otherwise indicated to the contrary, chemical structures that include one or more stereocenters which are illustrated herein without indicating absolute or relative stereochemistry encompass all possible stereoisomeric forms of the compound (e.g., diastereomers, enantiomers) and mixtures thereof. Structures with a single bold or dashed line, and at least one additional simple line, encompass a single enantiomeric series of all possible diastereomers.

As used herein, the term “about” is meant to account for variations due to experimental error. All measurements reported herein are understood to be modified by the term “about,” whether or not the term is explicitly used, unless explicitly stated otherwise. As used herein, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise.

The term “alkyl” means a straight or branched chain hydrocarbon. Representative examples of alkyl groups include methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, sec-butyl, pentyl and hexyl. Typical alkyl groups are alkyl groups having from 1 to 8 carbon atoms, which groups are commonly represented as C1-8 alkyl.

The term “compound”, as used herein is meant to include all stereoisomers, geometric isomers, tautomers, and isotopes of the structures depicted. Compounds herein identified by name or structure as one particular tautomeric form are intended to include other tautomeric forms unless otherwise specified.

All compounds, and pharmaceutically acceptable salts thereof, can be found together with other substances such as water and solvents (e.g., hydrates and solvates).

The term “cycloalkyl” means a cyclic, nonaromatic hydrocarbon. Representative examples of cycloalkyl groups include cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl and cycloheptyl. A cycloalkyl group can contain one or more double bonds. Representative examples of cycloalkyl groups that contain double bonds include cyclopentenyl, cyclohexenyl, cyclohexadienyl and cyclobutadienyl. Common cycloalkyl groups are C3-8 cycloalkyl groups.

The term “excipient”, as used herein, means any pharmaceutically acceptable additive, carrier, diluent, adjuvant or other ingredient, other than the active pharmaceutical ingredient (API), which is typically included for formulation and/or administration to a patient. Handbook of Pharmaceutical Excipients, 5th Edition, R. C. Rowe, P. J. Sheskey, and S. C. Owen, editors, Pharmaceutical Press, 2005, Hardback, 928, 0853696187.

For the terms “for example” and “such as” and grammatical equivalences thereof, the phrase “and without limitation” is understood to follow unless explicitly stated otherwise.

The term “halogen” or “halo” means F, Cl, Br or I.

The term “oxo”, when used as a substituent, means the ═O group, which is typically attached to a carbon atom.

The term “patient” means subjects including animals, such as dogs, cats, cows, horses, sheep and humans. Particular patients are mammals. The term patient includes males and females.

The term “patient in need” means a patient having, or at risk of having, one or more diseases or conditions where the Mcl-1 protein is involved, such as cancers. Identifying a patient in need can be in the judgment of a subject or a health care professional and can be subjective (e.g., opinion) or objective (e.g., measurable by a test or diagnostic method).

The phrases “parenteral administration” and “administered parenterally” as used herein means modes of administration other than enteral and topical administration, usually by injection, and includes, without limitation, intravenous, intramuscular, intraarterial, intrathecal, intracapsular, intraorbital, intracardiac, intradermal, intraperitoneal, transtracheal, subcutaneous, subcuticular, intraarticular, subcapsular, subarachnoid, intraspinal and intrastemal injection, and infusion.

Compositions suitable for parenteral injection may comprise physiologically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions, or emulsions, and sterile powders for reconstitution into sterile injectable solutions or dispersions. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents, or vehicles include water, ethanol, polyols (propylene glycol, polyethylene glycol, glycerol, and the like), suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

The term “pharmaceutically acceptable” is employed herein to refer to those ligands, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for administration to a patient, commensurate with a reasonable benefit/risk ratio.

The phrase “pharmaceutically acceptable carrier” as used herein means a pharmaceutically acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, excipient, solvent or encapsulating material. As used herein the language “pharmaceutically acceptable carrier” includes buffer, sterile water for injection, solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. Each carrier must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not injurious to the patient. Some examples of materials which can serve as pharmaceutically acceptable carriers include: (1) sugars, such as lactose, glucose, and sucrose; (2) starches, such as corn starch, potato starch, and substituted or unsubstituted β-cyclodextrin; (3) cellulose, and its derivatives, such as sodium carboxymethyl cellulose, ethyl cellulose, and cellulose acetate; (4) powdered tragacanth; (5) malt; (6) gelatin; (7) talc; (8) excipients, such as cocoa butter and suppository waxes; (9) oils, such as peanut oil, cottonseed oil, safflower oil, sesame oil, olive oil, corn oil, and soybean oil; (10) glycols, such as propylene glycol; (11) polyols, such as glycerin, sorbitol, mannitol, and polyethylene glycol; (12) esters, such as ethyl oleate and ethyl laurate; (13) agar; (14) buffering agents, such as magnesium hydroxide and aluminum hydroxide; (15) alginic acid; (16) pyrogen-free water; (17) isotonic saline; (18) Ringer's solution; (19) ethyl alcohol; (20) phosphate buffer solutions; and (21) other non-toxic compatible substances employed in pharmaceutical formulations.

The term “pharmaceutically acceptable salt” refers to the relatively non-toxic, inorganic and organic acid addition salts of a compound provided herein. These salts can be prepared in situ during the final isolation and purification of a compound provided herein, or by separately reacting the compound in its free base form with a suitable organic or inorganic acid, and isolating the salt thus formed. Representative salts include the hydrobromide, hydrochloride, sulfate, bisulfate, phosphate, nitrate, acetate, valerate, oleate, palmitate, stearate, laurate, benzoate, lactate, phosphate, tosylate, citrate, maleate, fumarate, succinate, tartrate, naphthylate, mesylate, glucoheptonate, lactobionate, laurylsulphonate salts, and amino acid salts, and the like. (See, for example, Berge et al. (1977) “Pharmaceutical Salts”, J. Pharm. Sci. 66: 1-19.)

The term “substituted” means that a hydrogen atom on a molecule or group is replaced with a group or atom. Typical substitutents include: halogen, C1-8alkyl, hydroxyl, C1-8alkoxy, —NRxRx, nitro, cyano, halo or perhaloC1-8alkyl, C2-8alkenyl, C2-8alkynyl, —SRx, —S(═O)2Rx, —C(═O)ORx, —C(═O)Rx, wherein each Rx is independently hydrogen or C1-C8 alkyl. It is noted that when the substituent is —NRxRx, the Rx groups may be joined together with the nitrogen atom to form a ring.

A group or atom that replaces a hydrogen atom is also called a substituent.

Any particular molecule or group can have one or more substituent depending on the number of hydrogen atoms that can be replaced.

The phrases “systemic administration”, “administered systemically”, “peripheral administration”, and “administered peripherally” as used herein mean the administration of a ligand, drug, or other material via route other than directly into the central nervous system, such that it enters the patient's system and thus, is subject to metabolism and other like processes, for example, subcutaneous administration.

The term “therapeutically effective amount” means an amount of a compound that ameliorates, attenuates or eliminates one or more symptom of a particular disease or condition, or prevents or delays the onset of one of more symptom of a particular disease or condition.

The terms “treating”, “treat” or “treatment” and the like include preventative (e.g., prophylactic) and palliative treatment.

The methods provided herein include the manufacture and use of pharmaceutical compositions, which include one or more of the compounds provided herein. Also included are the pharmaceutical compositions themselves.

In some embodiments, a compound provided herein may contain one or more acidic functional groups and, thus, is capable of forming pharmaceutically acceptable salts with pharmaceutically acceptable bases. The term “pharmaceutically acceptable salts” in these instances refers to the relatively non-toxic inorganic and organic base addition salts of a compound provided herein. These salts can likewise be prepared in situ during the final isolation and purification of the compound, or by separately reacting the purified compound in its free acid form with a suitable base, such as the hydroxide, carbonate, or bicarbonate of a pharmaceutically acceptable metal cation, with ammonia, or with a pharmaceutically acceptable organic primary, secondary, or tertiary amine. Representative alkali or alkaline earth salts include the lithium, sodium, potassium, calcium, magnesium, and aluminum salts, and the like. Representative organic amines useful for the formation of base addition salts include ethylamine, diethylamine, ethylenediamine, ethanolamine, diethanolamine, piperazine, and the like (see, for example, Berge et al., supra).

Wetting agents, emulsifiers, and lubricants, such as sodium lauryl sulfate and magnesium stearate, as well as coloring agents, release agents, coating agents, sweetening, flavoring, and perfuming agents, preservatives and antioxida

Examples of pharmaceutically acceptable antioxidants include: (1) water soluble antioxidants, such as ascorbic acid, cysteine hydrochloride, sodium bisulfate, sodium metabisulfite, sodium sulfite, and the like; (2) oil-soluble antioxidants, such as ascorbyl palmitate, butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), lecithin, propyl gallate, alpha-tocopherol, and the like; and (3) metal chelating agents, such as citric acid, ethylenediamine tetraacetic acid (EDTA), sorbitol, tartaric acid, phosphoric acid, and the like.

A pharmaceutical composition may also contain adjuvants such as preservatives, wetting agents, emulsifying agents, and dispersing agents. Prevention of the action of microorganisms may be ensured by the inclusion of various antibacterial and antifungal agents, for example, paraben, chlorobutanol, phenol sorbic acid, and the like. It may also be desirable to include tonicity-adjusting agents, such as sugars and the like into the compositions. In addition, prolonged absorption of the injectable pharmaceutical form may be brought about by the inclusion of agents which delay absorption such as aluminum monostearate and gelatin.

In some cases, in order to prolong the effect of one or more compounds provided herein, it is desirable to slow the absorption of the compound from subcutaneous or intramuscular injection. For example, delayed absorption of a parenterally administered compound can be accomplished by dissolving or suspending the compound in an oil vehicle.

The compounds of the present invention are administered to a patient in a therapeutically effective amount. The compounds can be administered alone or as part of a pharmaceutically acceptable composition or formulation. In addition, the compounds or compositions can be administered all at once, as for example, by a bolus injection, multiple times, such as by a series of tablets, or delivered substantially uniformly over a period of time, as for example, using transdermal delivery. The dose of the compound or composition can be varied over time. All combinations, delivery methods and administration sequences are contemplated.

The compounds of the present invention and in some embodiments, other additional pharmaceutically active compounds, can be administered to a patient either orally, rectally, parenterally, (for example, intravenously, intramuscularly, or subcutaneously) intracisternally, intravaginally, intraperitoneally, intravesically, locally (for example, powders, ointments or drops), or as a buccal or nasal spray. All methods that are used by those skilled in the art to administer a pharmaceutically active agent are contemplated.

Compositions prepared as described herein can be administered in various forms, depending on the disorder to be treated and the age, condition, and body weight of the patient, as is well known in the art. For example, where the compositions are to be administered orally, they may be formulated as tablets, capsules, granules, powders, or syrups; or for parenteral administration, they may be formulated as injections (intravenous, intramuscular, or subcutaneous), drop infusion preparations, or suppositories. For application by the ophthalmic mucous membrane route, they may be formulated as eye drops or eye ointments. These formulations can be prepared by conventional means in conjunction with the methods described herein, and, if desired, the active ingredient may be mixed with any conventional additive or excipient, such as a binder, a disintegrating agent, a lubricant, a corrigent, a solubilizing agent, a suspension aid, an emulsifying agent, or a coating agent.

Formulations suitable for oral administration may be in the form of capsules (e.g., gelatin capsules), cachets, pills, tablets, lozenges (using a flavored basis, usually sucrose and acacia or tragacanth), powders, troches, granules, or as a solution or a suspension in an aqueous or nonaqueous liquid, or as an oil-in-water or water-in-oil liquid emulsion, or as an elixir or syrup, or as pastilles (using an inert matrix, such as gelatin and glycerin, or sucrose and acacia) and/or as mouthwashes, and the like, each containing a predetermined amount of a compound provided herein as an active ingredient. A composition may also be administered as a bolus, electuary, or paste. Oral compositions generally include an inert diluent or an edible carrier.

Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of an oral composition. In solid dosage forms for oral administration (capsules, tablets, pills, dragees, powders, granules, and the like), the active ingredient can be mixed with one or more pharmaceutically acceptable carriers, such as sodium citrate or dicalcium phosphate, and/or any of the following: (1) fillers or extenders, such as starches, cyclodextrins, lactose, sucrose, saccharin, glucose, mannitol, and/or silicic acid; (2) binders, such as, for example, carboxymethylcellulose, microcrystalline cellulose, gum tragacanth, alginates, gelatin, polyvinyl pyrrolidone, sucrose, and/or acacia; (3) humectants, such as glycerol; (4) disintegrating agents, such as agar-agar, calcium carbonate, potato, corn, or tapioca starch, alginic acid, Primogel, certain silicates, and sodium carbonate; (5) solution retarding agents, such as paraffin; (6) absorption accelerators, such as quaternary ammonium compounds; (7) wetting agents, such as, for example, acetyl alcohol and glycerol monostearate; (8) absorbents, such as kaolin and bentonite clay; (9) lubricants, such a talc, calcium stearate, magnesium stearate, Sterotes, solid polyethylene glycols, sodium lauryl sulfate, and mixtures thereof; (10) a glidant, such as colloidal silicon dioxide; (11) coloring agents; and (12) a flavoring agent such as peppermint, methyl salicylate, or orange flavoring. In the case of capsules, tablets, and pills, the pharmaceutical compositions may also comprise buffering agents. Solid compositions of a similar type may also be employed as fillers in soft and hard-filled gelatin capsules using such excipients as lactose or milk sugars, as well as high molecular weight polyethylene glycols, and the like.

A tablet may be made by compression or molding, optionally with one or more accessory ingredients. Compressed tablets may be prepared using binder (for example, gelatin or hydroxypropylmethyl cellulose), lubricant, inert diluent, preservative, disintegrant (for example, sodium starch glycolate or cross-linked sodium carboxymethyl cellulose), surface-active or dispersing agent. Molded tablets may be made by molding in a suitable machine a mixture of a powdered compound moistened with an inert liquid diluent.

Tablets, and other solid dosage forms, such as dragees, capsules, pills, and granules, may optionally be scored or prepared with coatings and shells, such as enteric coatings and other coatings well known in the pharmaceutical-formulating art. They may also be formulated so as to provide slow or controlled release of the active ingredient therein using, for example, hydroxypropylmethyl cellulose in varying proportions to provide the desired release profile, other polymer matrices, liposomes, microspheres, and/or nanoparticles. They may be sterilized by, for example, filtration through a bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved in sterile water, or some other sterile injectable medium immediately before use. These compositions may also optionally contain opacifying agents and may be of a composition that they release the active ingredient(s) only, or preferentially, in a certain portion of the gastrointestinal tract, optionally, in a delayed manner. Examples of embedding compositions which can be used include polymeric substances and waxes. The active ingredient can also be in micro-encapsulated form, if appropriate, with one or more of the above-described excipients.

Liquid dosage forms for oral administration include pharmaceutically acceptable emulsions, microemulsions, solutions, suspensions, syrups, and elixirs. In addition to the active ingredient, the liquid dosage forms may contain inert diluents commonly used in the art, such as, for example, water or other solvents, solubilizing agents, and emulsifiers such as ethyl alcohol, isopropyl alcohol, ethyl carbonate, ethyl acetate, benzyl alcohol, benzyl benzoate, propylene glycol, 1,3-butylene glycol, oils (in particular, cottonseed, groundnut, corn, germ, olive, castor, and sesame oils), glycerol, tetrahydrofuryl alcohol, polyethylene glycols, and fatty acid esters of sorbitan, and mixtures thereof.

Besides inert diluents, the oral compositions can also include adjuvants such as wetting agents, emulsifying and suspending agents, sweetening, flavoring, coloring, perfuming, and preservative agents.

Suspensions, in addition to the active compound(s) may contain suspending agents as, for example, ethoxylated isostearyl alcohols, polyoxyethylene sorbitol and sorbitan esters, microcrystalline cellulose, aluminum metahydroxide, bentonite, agar-agar and tragacanth, and mixtures thereof.

Pharmaceutical compositions suitable for parenteral administration can include one or more compounds provided herein in combination with one or more pharmaceutically acceptable sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, or sterile powders which may be reconstituted into sterile injectable solutions or dispersions just prior to use, which may contain antioxidants, buffers, bacteriostats, solutes which render the formulation isotonic with the blood of the intended recipient or suspending or thickening agents.

In one embodiment, the IV formulation consists of a composition containing hydroxypropyl beta cyclodextrin within a pH range between 8-10 as a buffered or unbuffered solution. The IV formulation can be formulated as a sterile solution ready for injection, a sterile solution ready for dilution into an IV admixture or a sterile solid for reconstituion. The API in the IV formulation may exist as a free acid/base or an in situ salt.

Examples of suitable aqueous and nonaqueous carriers which may be employed in the pharmaceutical compositions provided herein include water for injection (e.g., sterile water for injection), bacteriostatic water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol such as liquid polyethylene glycol, and the like), sterile buffer (such as citrate buffer), and suitable mixtures thereof, vegetable oils, such as olive oil, injectable organic esters, such as ethyl oleate, and Cremophor EL™ (BASF, Parsippany, N.J.). In all cases, the composition must be sterile and should be fluid to the extent that easy syringability exists. Proper fluidity can be maintained, for example, by the use of coating materials, such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants.

The composition should be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms such as bacteria and fungi. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, and sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent that delays absorption, for example, aluminum monostearate and gelatin.

Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle, which contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, the methods of preparation are freeze-drying (lyophilization), which yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.

Injectable depot forms can be made by forming microencapsule or nanoencapsule matrices of a compound provided herein in biodegradable polymers such as polylactide-polyglycolide. Depending on the ratio of drug to polymer, and the nature of the particular polymer employed, the rate of drug release can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations are also prepared by entrapping the drug in liposomes, microemulsions or nanoemulsions, which are compatible with body tissue.

For administration by inhalation, the compounds can be delivered in the form of an aerosol spray from a pressured container or dispenser that contains a suitable propellant (e.g., a gas such as carbon dioxide) or a nebulizer. Such methods include those described in U.S. Pat. No. 6,468,798. Additionally, intranasal delivery can be accomplished, as described in, inter alia, Hamajima et al., Clin. Immunol. Immunopathol., 88(2), 205-10 (1998). Liposomes (e.g., as described in U.S. Pat. No. 6,472,375, which is incorporated herein by reference in its entirety), microencapsulation and nanoencapsulation can also be used. Biodegradable targetable microparticle delivery systems or biodegradable targetable nanoparticle delivery systems can also be used (e.g., as described in U.S. Pat. No. 6,471,996, which is incorporated herein by reference in its entirety).

Systemic administration of a therapeutic compound as described herein can also be by transmucosal or transdermal means. Dosage forms for the topical or transdermal administration of a compound provided herein include powders, sprays, ointments, pastes, creams, lotions, gels, solutions, patches, and inhalants. The active component may be mixed under sterile conditions with a pharmaceutically acceptable carrier, and with any preservatives, buffers, or propellants which may be required. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration can be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds are formulated into ointments, salves, gels, or creams as generally known in the art.

The ointments, pastes, creams, and gels may contain, in addition to one or more compounds provided herein, excipients, such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc, and zinc oxide, or mixtures thereof.

Powders and sprays can contain, in addition to a compound provided herein, excipients such as lactose, talc, silicic acid, aluminum hydroxide, calcium silicates, and polyamide powder, or mixtures of these substances. Sprays can additionally contain customary propellants, such as chlorofluorohydrocarbons and volatile unsubstituted hydrocarbons, such as butane and propane.

A compound provided herein can be administered by aerosol. This is accomplished by preparing an aqueous aerosol, liposomal preparation, or solid particles containing a compound or composition provided herein. A nonaqueous (e.g., fluorocarbon propellant) suspension could be used. In some embodiments, sonic nebulizers are used because they minimize exposing the agent to shear, which can result in degradation of the compound.

Ordinarily, an aqueous aerosol can be made by formulating an aqueous solution or suspension of the agent together with conventional pharmaceutically acceptable carriers and stabilizers. The carriers and stabilizers vary with the requirements of the particular composition, but typically include nonionic surfactants (TWEEN® (polysorbates), PLURONIC® (poloxamers), sorbitan esters, lecithin, CREMOPHOR® (polyethoxylates)), pharmaceutically acceptable co-solvents such as polyethylene glycol, innocuous proteins like serum albumin, sorbitan esters, oleic acid, lecithin, amino acids such as glycine, buffers, salts, sugars, or sugar alcohols. Aerosols generally are prepared from isotonic solutions.

Transdermal patches have the added advantage of providing controlled delivery of a compound provided herein to the body. Such dosage forms can be made by dissolving or dispersing the agent in the proper medium. Absorption enhancers can also be used to increase the flux of the compound across the skin. The rate of such flux can be controlled by either providing a rate controlling membrane or dispersing the compound in a polymer matrix or gel.

The pharmaceutical compositions can also be prepared in the form of suppositories or retention enemas for rectal and/or vaginal delivery. Formulations presented as a suppository can be prepared by mixing one or more compounds provided herein with one or more suitable nonirritating excipients or carriers comprising, for example, cocoa butter, glycerides, polyethylene glycol, a suppository wax or a salicylate, which is solid at room temperature, but liquid at body temperature and, therefore, will melt in the rectum or vaginal cavity and release the active agent. Formulations which are suitable for vaginal administration also include pessaries, tampons, creams, gels, pastes, foams, or spray formulations containing such carriers as are known in the art to be appropriate.

In one embodiment, the therapeutic compounds are prepared with carriers that will protect the therapeutic compounds against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Such formulations can be prepared using standard techniques, or obtained commercially (e.g., from Alza Corporation and Nova Pharmaceuticals, Inc). Liposomal suspensions (including liposomes targeted to selected cells with monoclonal antibodies to cellular antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811, which is incorporated herein by reference in its entirety for all purposes.

The compounds of the present invention are used in the treatment of diseases, disorders or symptoms mediated by Mcl-1 inhibition. Examples of diseases, disorders or symptoms mediated by Mcl-1 inhibition include, but are not limited to, cancers. Non-limiting examples of cancers include breast cancer, colorectal cancer, skin cancer, melanoma, ovarian cancer, kidney cancer, lung cancer, non-small cell lung cancer, lymphoma, non-Hodgkin's lymphoma, myeloma, multiple myeloma, leukemia, and acute myelogenous leukemia.

The cancers can include carcinomas (originating in the outer layer of cells of the skin and internal membranes, e.g., breasts, kidneys, lungs, skin); sarcomas (arising from connective tissue such as bone, muscle, cartilage, and blood vessels), and hematologic malignancies (e.g., lymphomas and leukemias, which arise in the blood or blood-forming organs such as the spleen, lymph nodes, and bone marrow). Cancer cells can include, for example, tumor cells, neoplastic cells, malignant cells, metastatic cells, and hyperplastic cells.

In an embodiment, the disease, disorder or symptom is a hyperproliferative disorder, e.g., a lymphoma, leukemia, carcinoma (e.g., renal, breast, lung, skin), multiple myeloma, or a sarcoma. In one embodiment, the leukemia is acute myeloid leukemia. In one embodiment, the hyperproliferative disorder is a relapsed or refractory cancer.

Actual dosage levels of the active ingredients in the pharmaceutical compositions provided herein may be varied so as to obtain an amount of the active ingredient which is effective to achieve the desired therapeutic response for a particular patient, composition, and mode of administration, without being toxic to the patient.

The specific dosage and dosage range depends on a number of factors, including the requirements of the patient, the severity of the condition or disease being treated, the pharmacokinetic characteristics of the compound(s) employed, and the route of administration. In some embodiments, the compositions provided herein can be provided in an aqueous solution containing about 0.1-10% w/v of a compound disclosed herein, among other substances, for parenteral administration. Typical dose ranges can include from about 0.01 to about 50 mg/kg of body weight per day, given in 1-4 divided doses. Each divided dose may contain the same or different compounds. The dosage will be a therapeutically effective amount depending on several factors including the overall health of a patient, and the formulation and route of administration of the selected compound(s).

Dosage forms or compositions containing a compound as described herein in the range of 0.005% to 100% with the balance made up from non-toxic carrier may be prepared. Methods for preparation of these compositions are known to those skilled in the art. The contemplated compositions may contain about 0.001%-100% active ingredient, in one embodiment from about 0.1 to about 95%, in another embodiment from about 75 to about 85%. Although the dosage will vary depending on the symptoms, age and body weight of the patient, the nature and severity of the disorder to be treated or prevented, the route of administration and the form of the drug, in general, a daily dosage of from about 0.01 to about 3,000 mg of the compound is recommended for an adult human patient, and this may be administered in a single dose or in divided doses. The amount of active ingredient which can be combined with a carrier material to produce a single dosage form will generally be that amount of the compound which produces a therapeutic effect.

The pharmaceutical composition may be administered at once, or may be divided into a number of smaller doses to be administered at intervals of time. It is understood that the precise dosage and duration of treatment is a function of the disease being treated and may be determined empirically using known testing protocols or by extrapolation from in vivo or in vitro test data. It is to be noted that concentrations and dosage values may also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular patient, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the concentration ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed compositions.

The precise time of administration and/or amount of the composition that will yield the most effective results in terms of efficacy of treatment in a given patient will depend upon the activity, pharmacokinetics, and bioavailability of a particular compound, physiological condition of the patient (including age, sex, disease type and stage, general physical condition, responsiveness to a given dosage, and type of medication), route of administration, etc. However, the above guidelines can be used as the basis for fine-tuning the treatment, e.g., determining the optimum time and/or amount of administration, which will require no more than routine experimentation consisting of monitoring the patient and adjusting the dosage and/or timing

The compounds of the present invention can be administered alone, in combination with other compounds of the present invention, or with other pharmaceutically active compounds or agents. The other pharmaceutically active compounds/agents can be intended to treat the same disease or condition as the compounds of the present invention or a different disease or condition. If the patient is to receive or is receiving multiple pharmaceutically active compounds or agents, the compounds can be administered simultaneously, or sequentially.

The compounds of the present invention, or pharmaceutically acceptable salts thereof, may be used in combination with one or more additional pharmaceutically active compounds/agents.

One or more additional pharmaceutically active compounds or agents may be administered separately, as part of a multiple dose regimen, from the compound of Formula I (e.g., sequentially, e.g., on different overlapping schedules with the administration of one or more compounds of Formula I (including any subgenera or specific compounds thereof). In other embodiments, the one or more additional compounds/agents may be part of a single dosage form, mixed together with the compound of Formula I in a single composition. In still another embodiment, the one or more additional compounds/agents can be given as a separate dose that is administered at about the same time that one or more compounds of Formula I are administered (e.g., simultaneously with the administration of one or more compounds of Formula I (including any subgenera or specific compounds thereof). Both the compound of Formula I and the one or more additional compounds/agents can be present at dosage levels of between about 1 to 100%, and more preferably between about 5 to 95% of the dosage normally administered in a monotherapy regimen.

In a particular embodiment, the additional pharmaceutically active compound/agent is a compound or agent that can be used to treat a cancer. For example, the additional pharmaceutically active compound/agent can be selected from antineoplastic agents, anti-angiogenic agents, chemotherapeutic agents, and peptidal cancer therapy agents. In another embodiment, the antineoplastic agents are selected from antibiotic-type agents, alkylating agents, antimetabolite agents, hormonal agents, immunological agents, interferon-type agents, kinase inhibitors, proteasome inhibitors, and combinations thereof.

As one aspect of the present invention contemplates the treatment of the disease/conditions with a combination of pharmaceutically active compounds that may be administered separately, the invention further relates to combining separate pharmaceutical compositions in kit form. The kit comprises two separate pharmaceutical compositions: a compound of the present invention, and a second pharmaceutical compound. The kit comprises a container for containing the separate compositions such as a divided bottle or a divided foil packet. Additional examples of containers include syringes, boxes, and bags. In some embodiments, the kit comprises directions for the use of the separate components. The kit form is particularly advantageous when the separate components are preferably administered in different dosage forms (e.g., oral and parenteral), are administered at different dosage intervals, or when titration of the individual components of the combination is desired by the prescribing health care professional.

The compounds of the present invention can be administered as pharmaceutically acceptable salts, esters, amides or prodrugs. The term “salts” refers to inorganic and organic salts of compounds of the present invention. The salts can be prepared in situ during the final isolation and purification of a compound, or by separately reacting a purified compound in its free base or acid form with a suitable organic or inorganic base or acid and isolating the salt thus formed. Representative salts include the hydrobromide, hydrochloride, sulfate, bisulfate, nitrate, acetate, oxalate, palmitiate, stearate, laurate, borate, benzoate, lactate, phosphate, tosylate, citrate, maleate, fumarate, succinate, tartrate, naphthylate, mesylate, glucoheptonate, lactobionate, and laurylsulphonate salts, and the like. The salts may include cations based on the alkali and alkaline earth metals, such as sodium, lithium, potassium, calcium, magnesium, and the like, as well as non-toxic ammonium, quaternary ammonium, and amine cations including, but not limited to, ammonium, tetramethylammonium, tetraethylammonium, methylamine, dimethylamine, trimethylamine, triethylamine, ethylamine, and the like. See, for example, S. M. Berge, et al., “Pharmaceutical Salts,” J Pharm Sci, 66: 1-19 (1977).

The term “prodrug” means compounds that are transformed in vivo to yield a compound of the present invention. The transformation may occur by various mechanisms, such as through hydrolysis in blood. A discussion of the use of prodrugs is provided by T. Higuchi and W. Stella, “Pro-drugs as Novel Delivery Systems,” Vol. 14 of the A.C.S. Symposium Series, and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.

To illustrate, if the compound of the invention contains a carboxylic acid functional group, a prodrug can comprise an ester formed by the replacement of the hydrogen atom of the acid group with a group such as (C1-C8 alkyl, (C2-C12)alkanoyloxymethyl, 1-(alkanoyloxy)ethyl having from 4 to 9 carbon atoms, 1-methyl-1-(alkanoyloxy)ethyl having from 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having from 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having from 5 to 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having from 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)aminomethyl having from 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolacton-4-yl, di-N,N—(C1-C2)alkylamino(C2-C3)alkyl (such as β-dimethylaminoethyl), carbamoyl-(C1-C2)alkyl, N,N-di(C1-C2)alkylcarbamoyl-(C1-C2)alkyl and piperidino-, pyrrolidino- or morpholino(C2-3)alkyl.

Similarly, if a compound of the present invention comprises an alcohol functional group, a prodrug can be formed by the replacement of the hydrogen atom of the alcohol group with a group such as (C1-C6)alkanoyloxymethyl, 1-((C1-C6)alkanoyloxy)ethyl, 1-methyl-1-((C1-C6)alkanoyloxy)ethyl, (C1-C6)alkoxycarbonyloxymethyl, N—(C1-C6)alkoxycarbonylaminomethyl, succinoyl, (C1-C6)alkanoyl, α-amino(C1-C4)alkanoyl, arylacyl and α-aminoacyl, or α-aminoacyl-α-aminoacyl, where each α-aminoacyl group is independently selected from the naturally occurring L-amino acids, —P(O)(OH)2, —P(O)(O(C1-C6)alkyl)2 or glycosyl (the radical resulting from the removal of a hydroxyl group of the hemiacetal form of a carbohydrate).

The compounds of the present invention may contain asymmetric or chiral centers, and therefore, exist in different stereoisomeric forms. It is contemplated that all stereoisomeric forms of the compounds as well as mixtures thereof, including racemic mixtures, form part of the present invention. In addition, the present invention contemplates all geometric and positional isomers. For example, if the compound contains a double bond, both the cis and trans forms (designated as Z and E, respectively), as well as mixtures, are contemplated.

Mixture of stereoisomers, such as diastereomeric mixtures, can be separated into their individual stereochemical components on the basis of their physical chemical differences by known methods such as chromatography and/or fractional crystallization. Enantiomers can also be separated by converting the enantiomeric mixture into a diasteromeric mixture by reaction with an appropriate optically active compound (e.g., an alcohol), separating the diastereomers and converting (e.g., hydrolyzing) the individual diastereomers to the corresponding pure enantiomers.

The compounds of the present invention may exist in unsolvated as well as solvated forms with pharmaceutically acceptable solvents such as water (hydrate), ethanol, and the like. The present invention contemplates and encompasses both the solvated and unsolvated forms.

It is also possible that compounds of the present invention may exist in different tautomeric forms. All tautomers of compounds of the present invention are contemplated. Those skilled in the art will recognize that the compound names and structures contained herein may be based on a particular tautomer of a compound. While the name or structure for only a particular tautomer may be used, it is intended that all tautomers are encompassed by the present invention, unless stated otherwise.

It is also intended that the present invention encompass compounds that are synthesized in vitro using laboratory techniques, such as those well known to synthetic chemists; or synthesized using in vivo techniques, such as through metabolism, fermentation, digestion, and the like. It is also contemplated that the compounds of the present invention may be synthesized using a combination of in vitro and in vivo techniques.

The compounds of the present invention may exist in various solid states including crystalline states and as an amorphous state. The different crystalline states, also called polymorphs, and the amorphous states of the present compounds are contemplated as part of this invention.

The syntheses of these common advanced intermediates are outlined below and further exemplification is found in the specific examples provided.

COMMON ADVANCED INTERMEDIATES

Intermediate AA11A (S)-6′-CHLORO-5-(((1R,2R)-2-((S)-1-HYDROXYALLYL)CYCLOBUTYL)METHYL)-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLIC ACID

STEP 1: 6-CHLORO-3,4-DIHYDRONAPHTHALEN-1(2H)-ONE

A 1 L beaker was charged with 6-amino-3,4-dihydro-1(2H)-naphthalenone (47.5 g, 1 eq), H2O (250 mL), and concentrated HCl (57 mL). The mixture was stirred with a plastic straw until dissolution and cooled to <0° C. NaNO2 (22.4 g) solution in H2O (45 mL) was added dropwise to the 6-aminotetralone HCl solution, while manually stirred, maintaining the temperature below 0° C. to give a dark red solution, which was used directly for chlorination.

To a 2 L 4-necked round bottom flask with open necks was added cuprous chloride (99 g, 1002 mmol) and concentrated HCl (393 mL, 4715 mmol) to give a dark solution which was cooled to 0° C. The diazotized solution (starting with 6-aminotetralone 95 g) was added portion-wise into the CuCl/HCl solution, maintaining the temp below 10° C. The resulting dark reaction mixture was allowed to warm to ambient temperature, stirred for 1 h and poured into a separatory funnel with DCM (150 mL). After partition, the aqueous layer was extracted with DCM (100 mL). The combined organic layers were washed with H2O (75 mL). To the DCM stream was added saturated NaHCO3 (100 mL) and Darco (15 g), the mixture was stirred for 15 min and then filtered through a celite pad. The layers were separated and the aqueous was washed with DCM (30 mL). The organic layers were combined and concentrated to give a brown oil, which could be used directly in the next step. The batch could be further purified by filtration through a plug of silica gel (˜100 g) rinsing with 10-50% EtOAc/heptane followed by concentration to give the product as a brown oil (87.5 g, 82% yield).

STEP 2: (R)-6-CHLORO-3,4-DIHYDRO-2H-SPIRO[NAPHTHALENE-1,2′-OXIRANE] AND (R)-6-CHLORO-3,4-DIHYDRO-2H-SPIRO[NAPHTHALENE-1,2′-OXIRANE]

A 2 L 4-necked RBF was charged 6-chloro-3,4-dihydro-1(2H)-naphthalenone (123 g, 681 mmol), trimethylsulfonium iodide (143 g, 701 mmol) and DMSO (1100 mL, 8.94 mL/g). Potassium hydroxide (76 g, 1362 mmol) (pellets) was added. The suspension was stirred at ambient temperature for 2 days after which time crude 1H NMR showed no remaining starting material. The solution was poured into 800 g of crushed ice, rinsed with MTBE (200 mL) and an additional portion of MTBE (700 mL) was added. The resulting mixture was stirred for 5 min. and after partition the bottom aqueous layer was extracted with MTBE twice (500 mL, 300 mL) and combined with the main MTBE extract. The combined organic stream was washed with brine (2×600 mL) and 330 g of Al2O3 (neutral) was added. The resulting suspension was stirred for 5 min. at 22° C., filtered and washed with MTBE (400 mL). The filtrate was concentrated to give the title compound as a red viscous oil (125 g, 94%).

STEP 3: (S)-6-CHLORO-1,2,3,4-TETRAHYDRONAPHTHALENE-1-CARBALDEHYDE AND (R)-6-CHLORO-1,2,3,4-TETRAHYDRONAPHTHALENE-1-CARBALDEHYDE

A 3 L 3-necked RBF was charged with racemic 6-chloro-3,4-dihydro-2H-spiro[naphthalene-1,2′-oxirane] (160 g, 822 mmol) and THF (1760 mL, 11 mL/g). After the batch was cooled to −8° C. with a dry ice/IPA bath, boron trifluoride diethyl etherate (5.07 mL, 41.1 mmol) was added over ˜3 min. An exotherm raised the batch temp to 10° C. instantly. The batch was stirred at −5 to 0° C. for 5 min, and LC analysis of a sample (quenched into cold NaHCO3 solution) showed complete conversion. The reaction was quenched by the addition of saturated NaHCO3 (300 mL) at −5° C. followed by MTBE (400 mL, 2.5 mL/g) and the mixture was transferred to a separatory funnel and rinsed with MTBE (240 mL, 1.5 mL/g). After partition, the aqueous layer was discarded along with some white solid (likely boric acid or borax). The organic layer was washed with brine (350 mL) and concentrated under reduced pressure to give a red oil. The crude material was used directly in the next step.

STEP 4: (6-CHLORO-1,2,3,4-TETRAHYDRONAPHTHALENE-1,1-DIYL)DIMETHANOL

Racemic 6-chloro-1,2,3,4-tetrahydro-1-naphthalenecarbaldehyde was charged onto a 3 L 3-necked RBF and rinsed with diethylene glycol (1000 mL, 5.88 mL/g). Formaldehyde 37% solution (652 mL, 8757 mmol) was added and the resulting biphasic emulsion was cooled to 5° C. with a dry ice/IPA bath. Potassium hydroxide (45% aqueous solution, 652 mL, 11.9 mol) was added over ˜30 min, maintaining the temperature below 20° C. After complete addition, the batch (20° C.) was slowly heated to 45° C. (Caution: Exothermic reaction) and aged for 1 h. HPLC showed complete conversion. Note: Some viscous insoluble tar was formed and it was removed prior to aqueous workup. To the batch was added brine (500 mL) and the mixture was extracted with DCM until the product content in the aqueous phase was less than 5%. The combined DCM extract was concentrated to ˜750 mL as a red oil, washed with H2O (500 mL), and the product started to crystallize out. Separated the suspension+DCM and discarded the clear top aqueous layer. The bottom layer was stirred in ice/H2O bath for 30 min, filtered and washed with DCM (˜100 mL) and H2O (100 mL). The product was dried under dry air/vacuum to give a first crop (113 g, 498 mmol, 57% yield). The DCM layer from the resulting mother liquor was separated and concentrated to 200-300 g (KF=0.5%), seeded, and stirred in ice/H2O bath for 30 min. The product was filtered, washed with DCM (˜50 mL), and dried in dry air/vacuum to give a second crop (14.3 g, 63.1 mmol, 7% yield) for a combined total yield of 6-chloro-1,2,3,4-tetrahydronaphthalene-1,1-diyl)dimethanol of 127 g (64%).

STEP 5: (S)-(6-CHLORO-1-(HYDROXYMETHYL)-1,2,3,4-TETRAHYDRONAPHTHALEN-1-YL)METHYL 4-BROMOBENZOATE

To a solution of 2,6-bis((R)-5,5-dibutyl-4-phenyl-4,5-dihydrooxazol-2-yl)pyridine (R,R-Kang Catalyst) (1.57 g, 2.64 mmol) in dry DCM (450 mL), copper(II) chloride (0.355 g, 2.64 mmol) was added and the resulting green colored solution was stirred at room temperature for 1 h. This solution was added via cannula to solution of (6-chloro-1,2,3,4-tetrahydronaphthalene-1,1-diyl)dimethanol (30 g, 132.73 mmol) in dry DCM (800 mL). The resulting mixture was cooled to −78° C. and a light green colored precipitation was observed in the reaction after some time. A solution of 4-bromobenzoyl chloride (34.77 g, 158.79 mmol) in DCM (500 mL) was then added slowly followed by the dropwise addition of N-ethyl-N-isopropylpropan-2-amine (20 g, 154 mmol).

The mixed fractions (˜4 g) were collected and repurified on a 220 g silica gel column using 10-20% acetone in hexanes leading to the isolation of desired (S)-5-(((1R,2R)-2-(((tert-butyldiphenylsilyl)oxy)methyl)cyclobutyl)methyl)-6′-chloro-4′,4′-difluoro-3′,4,4′,5-tetrahydro-2H,2′H-spiro[benzo[b][1,4]oxazepine-3,1′-naphthalene]-7-carboxylic acid (4.6 g, 6.42 mmol, 71.7% yield) and ((1R,2R)-2-(((tert-butyldiphenylsilyl)oxy)methyl)cyclobutyl)methanol (1.75 g, 4.94 mmol, 55.1% yield) The product only appeared 85% pure by NMR, but it was taken on to the next step.

After stirring for 1 h LC/MS showed 80% conversion and an additional charge of 1 mL TMS-diazomethane was added. After 10 min the mixture was quenched by addition of acetic acid and concentrated under rotary evaporation (in the hood, for safety). The material thus obtained was dried under high vacuum overnight. TLC in 1% acetone in hexanes or 2% ethyl acetate in hexanes did not show separation of a significant amount of impurities, so the material was taken on crude to the next step.

The residue was deposited on silica gel (25 g) and purified on a 330 g silica gel column eluting with 20% ethyl acetate in hexanes leading to partial separation of the desired product. Note: it is necessary to remove ˜15% impurity that had been carried since the reductive amination—likely a diasteroemeric product resulting from low ee of the cyclobutane. The mixed fractions (700 mg) were recycled through a 120 g column eluting with 20% ethyl acetate in hexanes and the purified (S)-methyl 6′-chloro-4′,4′-difluoro-5-(((1R,2R)-2-(hydroxymethyl)cyclobutyl)methyl)-3′,4,4′,5-tetrahydro-2H,2′H-spiro[benzo[b][1,4]oxazepine-3,1′-naphthalene]-7-carboxylate (combined total yield of 2.3 g, 4.68 mmol, 72.7%) was obtained cleanly, as a white solid.

NaHCO3) and stirred for 20 min. The organic layer was separated and washed with 50 ml dess martin extractor, then 25 mL sat. NaHCO3, dried over MgSO4, filtered, and concentrated. Crude NMR showed ˜5% of dess martin byproduct. The semipure material was passed through a 40 g silica gel column eluting with 100% DCM. The desired product dragged on the column but could be efficiently isolated (1.12 g, 94% yield).

Thionyl chloride, reagent plus (14.57 ml, 200 mmol) was then added drop wise via a syringe over a period of 20 minutes and the resulting mixture was heated to 98° C. for 45 minutes, then it was allowed to cool to room temperature. Rf of intermediate=0.42 eluting with 50% EtOAc in heptanes; use KMNO4 to visualize compound. The reaction mixture was then cooled in an ice-water bath, MeCN (120 mL) and water (150 mL) were added followed by ruthenium(III) chloride (0.035 g, 0.166 mmol). Sodium periodate (53.4 g, 250 mmol) was then added slowly portion wise over 30 minutes. The resulting biphasic brown mixture was stirred vigorously while allowed to reach room temperature for a period of 1.5 hour (internal temperature never increased above room temperature). TLC (50% EtOAc in heptanes) showed complete conversion. The crude mixture was then poured into ice water and extracted twice with 300 ml of diethyl ether.

To the solution was then added dilithium tetrachlorocuprate(ii), 0.1 m solution in tetrahydrofuran (69.7 mL, 6.97 mmol). The resulting mixture was stirred at −78° C. for 30 minutes and then allylmagnesium bromide, 1.0 m solution in diethyl ether (397 mL, 397 mmol) was added slowly via cannula over 80 minutes. The resulting mixture was stirred at 0° C. for 4 hours. The mixture was then quenched carefully with 200 mL water and allowed to reach room temperature at which time the volatiles were removed by rotary evaporation. To the aqueous residue was then added 50% H2SO4 (150 mL), the mixture was stirred for 5 minutes, Et2O was then added (400 mL) and the mixture was stirred vigorously at room temperature overnight.

Note: the orange color of DEAD was quenched almost immediately. Then a solution of (2S,3S)-3-methylhex-5-en-2-ol (from Intermediate EE22, Step 2; 17.6 g, 154 mmol; dried over sodium sulfate) was added drop wise as a solution in 50 ml of THF to the solution of phosphine/DEAD complex, via syringe-filter (0.45 um). The resulting ROH/DEAD/Bu3P mixture was aged at zero degrees for 15 minutes (solution turned light orange), at which time pyrimidine-2-thiol (49.3 g, 439 mmol) was added gradually to the top of the reaction vessel (as a solid) under positive argon pressure. The reaction was stirred at 0° C. for 1 hour then at room temperature 15 hours (Reaction not done at 12 hours by LCMS). Note: The reaction cannot be monitored by the disappearance of starting material. Use toluene as an internal standard. The crude reaction was then filtered to remove excess pyrimidine-2-thiol, diluted with 1000 ml of EtOAc, extracted twice with 500 ml of 1 N K2CO3 and once with 500 ml of brine. The aqueous layer was back extracted with 300 ml of EtOAc and the combined organic layers were dried over sodium sulfate. The organic solution was then filtered, the solvent removed by rotary evaporation and the crude filtered to remove the (E)-diethyl diazene-1,2-dicarboxylategenerated in the reaction. The filtrate (125 g) was passed through a silica plug (500 g silica, eluting with 2 L of DCM) to give 75 g of crude product after solvent removal. The crude product was purified again on a Combiflash (125 g gold silica column), eluting with 10% EtOAc in heptanes to give 2-(((2R,3S)-3-methylhex-5-en-2-yl)thio)pyrimidine (20.37 g, 98 mmol) as a light yellow oil.

The reaction was stirred at 45° C. for 5 minutes at which time hydrogen peroxide 30% in water (58.6 ml, 574 mmol) was added portion wise (10 ml at a time). Five minutes after the first portion of hydrogen peroxide was added, an exotherm was observed (65° C.), the reaction was taken out of oil bath, the addition was stopped and the flask placed in a water bath until temperature stabilizes. The flask was taken out of the water bath and the portion wise addition of hydrogen peroxide was continued at a rate in which the internal temperature stayed between 45° C. and 55° C. (about 40 minutes). Note: an ice bath was utilized if the temperature went above 60° C. and an oil bath was used if the temperature fell below 45° C. The reaction was then stirred at 45° C. for one hour. The reaction was diluted with 1400 ml of EtOAc and extracted two times with 500 ml of water and once with 500 ml of brine. The organic layer was dried over sodium sulfate, filtered, concentrated and the crude purified on a Combiflash (330 g gold silica column per 30 grams of crude), eluting with 0%-50% EtOAc in heptanes to give 2-(((2R,3S)-3-methylhex-5-en-2-yl)sulfonyl)pyrimidine (55.7 g, 232 mmol) as a light yellow oil.

Note: sodium methoxide was added portion wise, the internal temperature was monitored and the addition was slowed or the reaction was cooled in a water bath, never letting the internal temperature exceeded 30° C. The mixture was then concentrated by rotary evaporation and the waxy solid was triturated with MTBE (add 200 ml MTBE, stir for 1 hour using a spatula to break up clumps), filtered (use a stream of nitrogen over filter cake) and washed with 100 ml of cold MTBE to obtain sodium (2R,35)-3-methylhex-5-ene-2-sulfinate (46 g, 250 mmol) as a an off white solid.

The pH was checked (should be around pH=8.5) at which time the flask was place in a 45° C. oil bath and hydroxylamine-o-sulfonic acid (21.09 g, 187 mmol) was added portion wise over 90 minutes. The internal temperature of the reaction was monitored and the reaction was removed from the oil bath (if needed) to control exotherm (T max=55° C.). Note: the reaction was monitored by LCMS every 10 minutes and was done after 0.83 eq. of hydroxylamine-o-sulfonic acid was added. The mixture was then cooled to room temperature and was extracted with 1000 ml of EtOAc. The organic phase was extracted three times with 500 ml of 1 N HCl, two times with 300 ml of saturated sodium bicarbonate, once with 200 ml of brine, dried over sodium sulfate, filtered and concentrated by rotary evaporation to provide (2R,3S)-3-methylhex-5-ene-2-sulfonamide (32 g, 181 mmol) as a white solid.

STEP 1: (S)-ETHYL 2-((S)-1-HYDROXYETHYL)PENT-4-ENOATE

The following procedure was adapted from: Frater, G.; Müller, U.; Günther, W. Tetrahedron 1984, 40, 1269-1277.

A 2 L 3-neck flask and addition funnel were dried overnight in an oven. The joints were greased, then assembled hot, and cooled under a flush of argon. The center neck was equipped with a pressure equalizing addition funnel, one side was fitted with a septa and an argon inlet line, while the other side was equipped with an adaptor connected to an oil bubbler to monitor flow of argon through the reaction system. Once cooled, lithium bis(trimethylsilyl)amide, 1.0 M solution in tetrahydrofuran (830 mL, 830 mmol) was charged to the addition funnel, and then to the reactor. The reaction flask was cooled in an acetone/CO2 bath, and then a solution of (S)-(+)-3-hydroxy-n-butyric acid ethyl ester (49.4 mL, 378 mmol) in THF (50 mL) was added via cannula to the cooled reactor. This mixture stirred for 30 minutes, then was treated with allyl bromide (36.0 mL, 416 mmol) 10 minutes after the addition was complete, the reactor was removed from the bath and permitted to equilibrate to ambient temperature over 3 hours, when it was quenched by addition of saturated aqueous NH4Cl (300 mL). The solution was transferred to a separatory funnel. Water was added to dissolve the precipitated solids. The layers were mixed and then separated. The aqueous phase was extracted with EtOAc (2×250 mL). The combined extracts were washed with water (300 mL) and then brine (300 mL). The solution was dried over MgSO4, filtered and concentrated. 1H NMR analysis of the crude mixture showed that a considerable amount of HMDS was present. The concentrate was taken up in EtOAc (500 mL) then washed with 1N HCl (2×250 mL), water, and brine. The solution was dried with MgSO4, filtered and concentrated to afford a yellow oil. The oil was distilled at reduced pressure (4 mmHg, 60-70° C.) to yield a clear liquid, (S)-ethyl 2-((S)-1-hydroxyethyl)pent-4-enoate (55 g, 319 mmol, 84% yield). 1H NMR (400 MHz, CDCl3) δ 5.83-5.69 (m, 1H), 5.14-5.07 (m, 1H), 5.07-5.02 (m, 1H), 4.19 (q, J=7.1 Hz, 2H), 3.99-3.89 (m, 1H), 2.59 (d, J=7.4 Hz, 1H), 2.51-2.36 (m, 3H), 1.28 (t, J=7.1 Hz, 3H), 1.25 (d, J=6.5 Hz, 3H).

Lithium aluminum hydride, 1.0 M solution in THF (300 mL, 300 mmol) was cannulated to an oven dried 1 L Schlenk flask equipped with a nitrogen inlet through the side-arm. The flask was cooled in an ice-water bath. A solution of (9-ethyl 2-((S)-1-hydroxyethyl)pent-4-enoate (25.9 g, 150 mmol) in THF (30 mL) was added dropwise via cannula to the stirring cold solution, over 15 minutes. The cannula and solution flask were rinsed with 15 mL of THF. The solution was stirred and the reaction progress was monitored by TLC. Upon completion, the cold solution was slowly quenched with water (11.5 mL), 15% w/v aqueous NaOH (11.5 mL) and then more water (34 mL). Once the solution had warmed to RT, the solution was treated with Na2SO4, and was then filtered. The solids were washed twice with hot EtOAc (2×100 mL). Concentration of the solution yielded a clear oil, characterized as (2R,3S)-2-allylbutane-1,3-diol by 1H NMR, of about 90% purity. The material was not purified further. 1H NMR (400 MHz, CDCl3) δ 5.80 (tdd, J=17.2, 10.0, 7.1 Hz, 1H), 5.12-5.00 (m, 2H), 3.96-3.86 (m, 2H), 3.67 (dd, J=11.2, 6.3 Hz, 1H), 2.80 (br. s, 2H), 2.29-2.18 (m, 1H), 2.16-2.05 (m, 1H), 1.61-1.51 (m, 1H), 1.28 (dd, J=6.3, 1.0 Hz, 3H).

The solution was stirred at ambient temperature (ca. 2 h) then quenched with water (50 mL). The layers were separated, and the aqueous layer was extracted with DCM (25 mL). The combined organic layers were washed with brine, dried over Na2SO4, filtered and concentrated to yield clear oil. The oil was purified by column chromatography eluting with a gradient of 5 to 20% EtOAc/hexanes, on a 80 g SiO2 column, to yield (2S,3R)-3-(((tert-butyldimethylsilyl)oxy)methyl)hex-5-en-2-ol (4.47 g, 18.29 mmol, 77% yield). 1H NMR (400 MHz, CDCl3) δ 5.78 (dddd, J=16.8, 10.0, 7.8, 6.3 Hz, 1H), 5.10-5.01 (m, 2H), 3.93 (dd, J=10.2, 3.7 Hz, 1H), 3.85 (qdd, J=6.3, 6.1, 5.1 Hz, 1H), 3.65 (dd, J=10.2. 6.1 Hz, 1H), 3.58 (d, J=5.1 Hz, 1H), 2.28-2.20 (m, 1H), 2.14-2.05 (m, 1H), 1.59-1.50 (m, 1H), 1.25 (d, J=6.3 Hz, 3H), 0.91 (s, 9H), 0.09 (s, 6H).

The solution was removed from the bath after 1 hour and stirred while equilibrating to ambient temperature. Water was added to the reaction mixture, and the layers were separated. The aqueous layer was extracted with DCM (2×) then the combined organic layers were washed with 1N HCl (2×25 mL) and then saturated aqueous NaHCO3 (25 mL), which caused the formation of an emulsion that could not be broken by addition of brine, additional NaCl, water, or hexane. Finally, the mixture was diluted with ˜300 mL EtOAc, and separation was observed. The layers were separated, and then the organic layer was washed with brine (50 mL), dried over MgSO4, filtered and concentrated to give a clear oil.

The oil was taken up in DMF (65 mL) and treated with 2-mercapto-pyrimidine (2.22 g, 19.79 mmol) and potassium carbonate (2.73 g, 19.75 mmol) then the reaction mixture was stirred at ambient temperature for 18 hours. 1H NMR analysis of an aliquot revealed minimal conversion. The reaction mixture was heated to 60° C.; within 5 hours the reaction failed to reach completion. More K2CO3 (300 mg) and 2-mercapto-pyrimidine (200 mg) were added and the solution stirred overnight (16 h). After cooling to room temperature, the reaction mixture was partitioned between water and EtOAc. The layers were separated, and the aqueous layer was extracted once with EtOAc. The combined organic extracts were washed thrice with brine, then dried over MgSO4, filtered and concentrated to yield an oily yellow residue.

STEP 1: (1R,2R)-CYCLOBUTANE-1,2-DIYLDIMETHANOL AND (1S,2S)-CYCLOBUTANE-1,2-DIYLDIMETHANOL

Trans-1,2-cyclobutanedicarboxylic acid (Synthon; 5 g, 34.7 mmol) in THF (34.7 mL) was transferred into a 3 neck round bottom flask fitted with an addition funnel, nitrogen inlet and thermometer and the flask was cooled to 0° C. Borane tetrahydrofuran complex (Sigma Aldrich, 1M in THF; 83 mL, 83 mmol) was then cannulated into the addition funnel. The borane tetrahydrofuran complex was then added into the stirred cooled mixture dropwise over 15 minutes (hydrogen gas evolved rapidly). After the addition was completed the reaction was allowed to warm to ambient temperature overnight under a N3 atmosphere. After this time the reaction was treated with MeOH (50 mL) and then the mixture was transferred to a 500 mL flask and evaporated in vacuo. The solution was taken back up in MeOH and concentrated again. This process was repeated 3 times. The final clear grey oil was kept under vacuum for 3 hours to give (1R,2R)-cyclobutane-1,2-diyldimethanol and (1S,2S)-cyclobutane-1,2-diyldimethanol (3.5 g, 30.1 mmol, 87% yield).

To a suspension of sodium hydride (0.861 g, 21.52 mmol) in THF (86 mL) at 0° C. under a N2 atmosphere was added a solution of (1R,2R)-cyclobutane-1,2-diyldimethanol and (1S,2S)-cyclobutane-1,2-diyldimethanol (2.5 g, 21.52 mmol) in THF (20 mL) dropwise over 20 minutes. After this time the reaction was heated at 55° C. for 45 minutes and then it was cooled down to 0° C. and treated with a solution of TBS-Cl (Sigma Aldrich; 3.24 g, 21.52 mmol) in THF (15 mL). The reaction was stirred at ambient temperature overnight. After this time the reaction was quenched with NH4Cl (sat. aq. solution) and diluted with EtOAc. The separated aqueous layer was extracted with EtOAc, and the combined organic extracts were washed with brine, dried over MgSO4, filtered and evaporated in vacuo. Column chromatography (80 g SiO2, hexanes:EtOAc, 1:0 to 4:1) gave ((1R,2R)-2-(((tert-butyldimethylsilyl)oxy)methyl)cyclobutyl)methanol and ((1S,2S)-2-(((tert-butyldimethylsilyl)oxy)methyl)cyclobutyl)methanol (3.45 g, 14.97 mmol, 69.6% yield).

STEP 3: ((1R,2R)-2-(((TERT-BUTYLDIMETHYLSILYL)OXY)METHYL)CYCLOBUTYL)METHYL METHANE SULFONATE AND ((1S,2S)-2-(((TERT-BUTYLDIMETHYLSILYL)OXY)METHYL)CYCLOBUTYL)METHYL METHANESULFONATE

To a stirred solution of ((1R,2R)-2-(((tert-butyldimethylsilyl)oxy)methyl)cyclobutyl)methanol and ((1S,2S)-2-(((tert-butyldimethylsilyl)oxy)methyl)cyclobutyl)methanol (3.45 g, 14.97 mmol) in DCM (74.9 mL) at 0° C. was added triethylamine (3.13 mL, 22.46 mmol) followed by methanesulfonyl chloride (1.283 mL, 16.47 mmol). The reaction was stirred at ambient temperature for 2 hours. After this time the reaction was transferred to a separating funnel and successively washed with 1M HCl, NaHCO3 and brine. The separated organic layer was dried over MgSO4, filtered and evaporated in vacuo to give ((1R,2R)-2-(((tert-butyldimethylsilyl)oxy)methyl)cyclobutyl)methyl methane sulfonate and ((1S,2S)-2-(((tert-butyldimethylsilyl)oxy)methyl)cyclobutyl)methyl methanesulfonate (4.15 g, 13.45 mmol, 90% yield).

STEP 1: BENZYL 2-CYCLOPROPYLIDENEACETATE

The cyclopropanone precursor, (1-ethoxycyclopropoxy)trimethylsilane (Wonda, 500 g, 2.866 mol), was dissolved in methanol (1.4 L) and the resulting solution was stirred at ambient temperature for two days. Methanol was removed in vacuo to provide the crude cyclopropanone ethyl hemiacetal intermediate. This material was redissolved in anhydrous chloroform (3 L), benzoic acid (63.7 g, 0.52 mol) was added, and the resulting reaction mixture was heated at reflux for 10 min under an atmosphere of dry nitrogen. A solution of benzyl 2-(triphenylphosphoranylidene)acetate (Wonda, 1.07 kg, 2.61 mol) dissolved in the minimum volume of chloroform was then added to the reaction mixture dropwise. On completion of the reaction as assessed by TLC analysis, the mixture was allowed to cool to room temperature and the solvent was removed on a rotary evaporator. The residue was purified by flash chromatography (60-120 mesh silica gel) using a solvent gradient of 0 to 5% ethyl acetate in hexanes to afford the title compound (331 g, 61% yield) as a colorless oil.

STEP 2: (S)-BENZYL 2-HYDROXY-2-(1-HYDROXYCYCLOPROPYL)ACETATE, PREDOMINANTLY AND (R)-BENZYL 2-HYDROXY-2-(1-HYDROXYCYCLOPROPYL)ACETATE (PREDOMINANTLY (S))

To an ice-cooled solution of benzyl 2-cyclopropylideneacetate (331 g, 1.76 mol) in a mixture of tert-butanol (8.8 L) and water (8.8 L) was added AD-mix β (Aldrich, 2.45 kg). The resulting orange suspension was vigorously stirred at 0° C. Ten minutes later, methanesulfonamide (Alfa Aesar, 167 g, 1.76 mol) was added and the reaction mixture was stirred at 0° C. for 16 h, after which time solid sodium sulfite (830 g, 6.58 mol) was added. Stirring at 0° C. for was continued for 15 minutes. The reaction mixture was diluted with ethyl acetate (10 L). Layers were separated and the aqueous layer was extracted with ethyl acetate (2×3 L). The combined organic layers was washed with brine again, dried over sodium sulfate, filtered and concentrated in vacuo to yield the crude material, which was purified by column chromatography (60-120 mesh silica), eluting with a gradient of 0 to 40% ethyl acetate in hexanes, to afford the title compound as a translucent oil (260 g, 66% yield). Predominantly (S) benzyl 2-hydroxy-2-(1-hydroxycyclopropyl)acetate prepared in this manner typically had 86-89% enantiomeric excess as determined by chiral HPLC [Chiral pak IC column (250 mm×4.6 mm); Mobile Phase: n-hexane:EtOH:90:10. Run Time: 20 min. Flow rate: 1 ml/min. Retention time (minor peak)-9.35 (5.4%); Retention time (major peak)-11.67 (94.6%)] and crystallized upon extended standing or cooling to give a white solid. An optional recrystallization procedure was implemented in some cases. For example, in one experiment, 37.9 g of predominantly (S) benzyl 2-hydroxy-2-(1-hydroxycyclopropyl)acetate was dissolved in 400 mL hot hexanes to which was added the minimum volume of ethyl acetate required to produce a solution upon cooling. Diethyl ether (10 mL) was added to the solution, and it was stored at ca. −20° C. overnight. On the following day, the white crystals were collected by vacuum filtration, dried under vacuum, and found to weigh 29.3 g (77% recovery for crystallization) and to have an enantiomeric excess of ca. 89% as assessed by chiral HPLC.

STEP 3: (R)-1-(2-((TERT-BUTYLDIPHENYLSILYL)OXY)-1-HYDROXYETHYL)CYCLOPROPANOL AND (S)-1-(2-((TERT-BUTYLDIPHENYLSILYL)OXY)-1-HYDROXYETHYL)CYCLOPROPANOL (PREDOMINANTLY (R))

Predominantly (S) benzyl 2-hydroxy-2-(1-hydroxycyclopropyl)acetate (13.0 g, 58.5 mmol, recrystallized by the procedure described in Step 2) was dissolved in anhydrous tetrahydrofuran (200 mL) under an atmosphere of nitrogen and the resulting solution was cooled to ° C. in an ice water bath. Lithium borohydride (2 M solution in tetrahydrofuran, 120 ml, 240 mmol) was added to the reaction mixture over the course of ten minutes. The reaction mixture was then allowed to gradually warm to room temperature and aliquots were intermittently removed to facilitate reaction monitoring by NMR (aliquots were quenched by addition of methanol, acidified with acetic acid, concentrated to dryness, redissolved in THF-d8, filtered, concentrated to dryness again, and finally redissolved in the desired NMR solvent, methanol-d4). After 110 minutes, the reaction had gone to completion and the mixture was again cooled to 0° C. After 45 minutes, the reaction was quenched by gradual addition of methanol (150 mL) followed by dropwise addition of a solution of ammonium acetate (119 g) in methanol (500 mL). The mixture was then acidified by addition of acetic acid (25 mL) and all volatiles were removed in vacuo. Three successive evaporations of methanol (250 mL) from the resulting residue were performed to remove boron byproducts as (volatile) trimethylborate. The boron-depleted residue was suspended in tetrahydrofuran and filtered under vacuum, washing the filter cake copiously with tetrahydrofuran (total volume of THY used=1 L). The filtrate was concentrated in vacuo to provide 14.1 g of the crude triol intermediate as a viscous, pale-yellow syrup containing benzyl alcohol and small amounts of residual acetic acid.

The crude triol was redissolved in anhydrous N,N-dimethylformamide (290 mL), and 1H-imidazole (20.21 g, 297 mmol) and tert-butylchlorodiphenylsilane (37 mL, 144 mmol) were sequentially added to this solution. The resulting reaction mixture was stirred at ambient temperature for 19 hours under an atmosphere of dry nitrogen. On completion of the reaction (as assessed by GC analysis), the mixture was diluted in ether (250 mL) and washed with 5% (w/w) aqueous LiCl (250 mL). The aqueous layer was back-extracted with three 100 mL portions of ether and the combined organics were subjected to a second wash with aqueous LiCl as described above. The organics were then sequentially washed with water (250 mL) and brine (250 mL), and were then dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting residue was purified by flash chromatography (330 g silica gel column eluted with a gradient of 0 to 40% ethyl acetate in hexanes) to provide the title compounds (17.7 g, 85% yield from benzyl 2-hydroxy-2-(1-hydroxycyclopropyl)acetate) as a waxy, white crystalline solid.

STEP 4: (S)-2-(((TERT-BUTYLDIPHENYLSILYL)OXY)METHYL)CYCLOBUTANONE, PREDOMINANTLY AND (R)-2-(((TERT-BUTYLDIPHENYLSILYL)OXY)METHYL)CYCLOBUTANONE (PREDOMINANTLY (S), 78-81% ee)

An oven-dried 500 mL RBF containing a stir bar was sealed with a septum and placed under an atmosphere of dry nitrogen using a dual-manifold. The flask was charged with 1-(2-((tert-butyldiphenylsilyl)oxy)-1-hydroxyethyl)cyclopropanol (predominantly (R) enantiomer mixture, 11.970 g, 33.6 mmol) and 300 mL pyridine. Once all of the diol starting material had dissolved, the resulting solution was cooled in an acetonitrile/dry ice mixture to ca. −40° C., and the nitrogen line was replaced with an Argon balloon. Methanesulfonyl chloride (5.30 mL, 68.5 mmol) was added to the reaction mixture via syringe over the course of five minutes. The reaction mixture was stirred at −35° C. for 18 h inside a cryocool apparatus using acetone as the coolant medium. The reaction mixture was then allowed to warm to ambient temperature over the course of thirty minutes, after which time additional mesyl chloride (530 μL, 784 mg, 6.85 mmol) was added. Stirring at room temperature was continued for forty minutes. The reaction mixture was then cooled to ca. −10° C. in an acetonitrile/dry ice slurry and poured into 250 mL of ice-water. The crude product was extracted into ether from the water layer via multiple rounds of extraction with fresh solvent, with the total volume of ether used being 800 mL. The combined organics were then washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo to give a crude residue that was further purified by chromatography on a 220 g silica gel column eluted with a gradient of 0 to 25% ethyl acetate in hexanes to provide the title compounds (8.12 g, 71% yield) as a semi-crystalline white solid. The cyclobutanone prepared in this manner typically had enantiomeric excesses ranging from 78-81% as assessed by Chiral SFC, corresponding to enantiomer ratios ranging from 8.1:1 to 9.5:1. Absolute stereochemistry of the major enantiomer of the cyclobutanone was confirmed by stereospecific conversion to (1R,2R)-2-(((tert-butyldiphenylsilyl)oxy)methyl)cyclobutanecarbaldehyde, reductive amination of the aldehyde with Intermediate AA11A, Step 12B and subsequent desilylation to provide a sample of Intermediate AA11A, Step 19B; the NMR spectral features of this material were identical to those of an authentic sample of Intermediate AA11A, Step 19B.

STEP 5: (1S,2S)-2-(((TERT-BUTYLDIPHENYL SILYL)OXY)METHYL)CYCLOBUTANOL AND (1R,2R)-2-(((TERT-BUTYLDIPHENYLSILYL)OXY)METHYL)CYCLOBUTANOL (PREDOMINANTLY (1S,2S))

An oven-dried 100 mL round bottom flask was charged with 2-(((tert-butyldiphenylsilyl)oxy)methyl)cyclobutanone (predominantly (S) with an enantiomer ratio of ca. 9:1, prepared in Step 4, 1.20 g, 3.54 mmol) and placed under a nitrogen atmosphere. The cyclobutanone was dissolved in anhydrous tetrahydrofuran (35 mL) and the resulting solution was cooled to −78° C. in a dry ice/acetone bath. L-Selectride (1 M in THF, 5.40 ml, 5.40 mmol) was added via syringe, and the reaction mixture was allowed to gradually warm to ambient temperature. After 1 hour, 20 minutes, the reaction was quenched by cautious addition of saturated ammonium chloride and partitioned between ethyl acetate and saturated ammonium chloride, back-extracting the aqueous phase with several portions of ethyl acetate. The combined organics were washed with brine, dried over magnesium sulfate, filtered, and concentrated in vacuo to give the crude product, which was further purified by silica gel chromatography to provide the title compounds (1.14 g, 94% yield).

STEP 6: (((1S,2R)-2-(ALLYLTHIO)CYCLOBUTYL)METHOXY)(TERT-BUTYL)DIPHENYLSILANE AND (((1R,2S)-2-(ALLYLTHIO)CYCLOBUTYL)METHOXY)(TERT-BUTYL)DIPHENYLSILANE (PREDOMINANTLY (1S,2R))

Methanesulfonyl chloride (0.270 mL, 3.49 mmol) was added to a stirred, ice-cooled solution of cis-2-(((tert-butyldiphenylsilyl)oxy)methyl)cyclobutanol (predominantly (1S,2S) enantiomer mixture, prepared in Step 5, 1.13 g, 3.33 mmol) and N-ethyl-N-isopropylpropan-2-amine (Hünig's base, 1.2 ml, 6.89 mmol) in anhydrous dichloromethane (16 mL) under an atmosphere of nitrogen. The mixture was allowed to gradually warm to room temperature. After three hours, 35 minutes, the mixture was cooled again to ° C. in an ice-water bath. Fifteen minutes later, the mixture was diluted in 75 mL of ice-cooled dichloromethane and the resulting solution was washed with ice-cooled 1 M aqueous hydrochloric acid (2×). The combined aqueous layers were back-extracted with two portions of dichloromethane and the combined organics were sequentially washed with ice-cooled water, ice-cooled saturated sodium bicarbonate, and brine. The organics were dried over magnesium sulfate, filtered and concentrated in vacuo to provide the crude mesylate ester intermediate as a yellow syrup (1.395 g, 100% crude yield).

Technical grade prop-2-ene-1-thiol, (Sigma Aldrich, 1.1 mL, 10.68 mmol) was added cautiously via syringe to a stirred slurry of sodium hydride (60% dispersion in mineral oil, 0.36 g, 9.00 mmol) in ice-cooled, degassed anhydrous N,N-dimethylformamide under an argon atmosphere. Once the addition was complete, the reaction mixture was allowed to warm to room temperature over the course of 22 minutes, after which a solution of the crude mesylate generated above (1.38 g, the amount remaining after analytical samples had been taken) in anhydrous, degassed N,N-dimethylformamide (12 mL) was added to the allyl thiolate solution. After five minutes, the resulting stirred reaction mixture was heated in an oil bath at 65° C. for two hours, 30 minutes. Upon cooling, 14 g of maleimide-functionalized silica gel (0.66 mmol/g maleimide loading; obtained from Silicycle) was added to the reaction mixture, giving a dark red slurry that was stirred at ambient temperature for 30 minutes and subsequently filtered, washing the filter cake with copious amounts of ethyl acetate. The filtrate was washed with 5% (w/w) aqueous LiCl, and the LiCl layer was back-extracted with two 75 mL portions of diethyl ether. The combined organics were washed sequentially with water, 15% (w/w) aqueous citric acid, water (once more), saturated sodium bicarbonate (2×), brine, and were dried over magnesium sulfate, filtered and concentrated in vacuo to give the crude thioether product, which was further purified by chromatography on silica gel using an eluent gradient of 0 to 20% ethyl acetate in hexanes. Fractions containing predominantly the desired product along with small amounts of nearly co-eluting impurities were pooled and stripped of solvents in vacuo to give the title compound as 1.7 g of an oil, a mixture of compounds containing minor quantities of an unidentified impurity that was removed much more readily after Step 7.

STEP 7: ((1S,2R)-2-(ALLYLTHIO)CYCLOBUTYL)METHANOL AND ((1R,2S)-2-(ALLYLTHIO)CYCLOBUTYL)METHANOL (PREDOMINANTLY (1S,2R))

Tetrabutylammonium fluoride (1 M in THF, 5.40 ml, 5.40 mmol) was added to a stirred, ice-cooled solution of trans-((2-(allylthio)cyclobutyl)methoxy)(tert-butyl)diphenylsilane, predominantly (1S,2R) (1.07 g, 2.70 mmol) in anhydrous tetrahydrofuran (18 mL) under an atmosphere of dry nitrogen. Following addition, the reaction mixture was allowed to warm to room temperature. After 4 h, the reaction mixture was partitioned between ether and saturated aqueous ammonium chloride. The aqueous layer was back-extracted with three portions of ether, and the combined organics were washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo to give the crude alcohol, which was further purified by flash chromatography (80 g silica gel column eluted with a gradient of 0 to 30% ethyl acetate in hexanes) to provide 445 mg of a clear oil. NMR analysis showed this material to be the desired product, containing ca. 21 mol % residual ethyl acetate of chromatography. The mass of desired product present in the sample could therefore be estimated as 387 mg, corresponding to a 91% yield.

STEP 8: (S)-TERT-BUTYL 5-(((1S,2R)-2-(ALLYLTHIO)CYCLOBUTYL)METHYL)-6′-CHLORO-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLATE AND (S)-TERT-BUTYL 5-(((1R,2S)-2-(ALLYLTHIO)CYCLOBUTYL)METHYL)-6′-CHLORO-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLATE OR [(S)-TERT-BUTYL 5-(((1S,2R)-2-(ALLYLTHIO)CYCLOBUTYL)METHYL)-6′-CHLORO-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLATE AND (S)-TERT-BUTYL 5-(((1S,2S)-2-(ALLYLTHIO)CYCLOBUTYL)METHYL)-6′-CHLORO-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLATE OR [(S)-TERT-BUTYL 5-(((1S,2R)-2-(ALLYLTHIO)CYCLOBUTYL)METHYL)-6′-CHLORO-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLATE AND (S)-TERT-BUTYL 5-(((1R,2R)-2-(ALLYLTHIO)CYCLOBUTYL)METHYL)-6′-CHLORO-3′,4,4′,5-TETRAHYDRO-2H,2′H-SPIRO[BENZO[B][1,4]OXAZEPINE-3,1′-NAPHTHALENE]-7-CARBOXYLATE

Water (50 μL) was suspended in a solution of trans-(2-(allylthio)cyclobutyl)methanol (predominantly (1S,2R), prepared in Step 7, 222 mg, 1.403 mmol) in dichloromethane (13 mL), and the resulting biphasic mixture was vigorously stirred at ambient temperature. After 15 minutes, the water appeared to be thoroughly dispersed throughout the reaction medium, and 1,1,1-Triacetoxy-1,1-dihydro-1,2-benziodoxol-3(1H)-one (Dess-Martin periodinane, 1.18 g, 2.78 mmol) was added. The stirred reaction mixture was aged for 3.5 h and then diluted in additional dichloromethane. The excess oxidant was quenched by addition of 1 M aqueous sodium thiosulfate (a volume roughly equal to that of the organics). The resulting biphasic mixture was stirred at room temperature until both phases became clear and was then partitioned between ether and 1 M sodium thiosulfate. The organic phase was washed with sequentially with 1 M sodium thiosulfate, saturated sodium bicarbonate (6×) and brine, dried over magnesium sulfate and concentrated in vacuo cautiously (so as not to evaporate the desired aldehyde). The resulting oil weighed 161 mg and appeared by proton NMR to be the contain principally the desired aldehyde intermediate, along with minor amounts of residual ether.

(S)-tert-butyl 6′-chloro-3′,4,4′,5-tetrahydro-2H,2′H-spiro[benzo[b][1,4]oxazepine-3,1′-naphthalene]-7-carboxylate (Intermediate AA11A, Step 12B, 237 mg, 0.593 mmol) and a solution of the crude intermediate aldehyde trans-2-(allylthio)cyclobutane carbaldehyde (predominantly (1S,2R), 151.7 mg, 0.884 mmol) were dissolved in a mixture of anhydrous dichloromethane (4400 μL) and acetic acid (2200 μL). The resulting stirred reaction mixture was cooled to 0° C. in an ice-water bath. After the mixture had been aged for 20 minutes at this temperature, a solution of sodium cyanoborohydride (18.5 mg, 0.295 mmol) in anhydrous tetrahydrofuran (500 μL) was added to it over the course of 90 minutes using a dry gas-tight syringe mounted on a syringe pump. The reaction mixture was then allowed to warm to ambient temperature and was aged for an additional 11 h, after which it was diluted in ethyl acetate and poured into a slurry of ca. 40 g of ice suspended in 70 mL 1 M aqueous sodium hydroxide. The crude product mixture was extracted into ethyl acetate and the aqueous layer was back-extracted with two portions of ethyl acetate. The combined organics were sequentially washed with two portions of pH 7 phosphate buffer and two portions of brine, dried over magnesium sulfate, filtered, and stripped in vacuo to give a residue which was further purified by flash chromatography (24 g silica gel column eluting with a gradient of 0 to 40% (99:1 ethyl acetate:acetic acid) in hexanes) to provide the title compounds as a white foam (229 mg, 30% combined yield over two steps based on trans-(2-(allylthio)cyclobutyl)methanol, 72% combined yield for the reductive amination based on Intermediate AA11A, Step 12B).

Additional quantities of sulfonamide (51.4 mg, 0.38 mmol) and catalyst (7.0 mg, 0.011 mmol) were added at reaction times of 22 and 33 minutes, respectively. After a total reaction time of 90 minutes, the mixture was concentrated in vacuo and purified by silica gel chromatography, using a solvent gradient of 0 to 40% (99:1 ethyl acetate:acetic acid) in hexanes, to provide a mixture of isomeric metathesis cross-coupling products as a semi-solid yellow residue (90.4 mg, 57% material recovery).

A stirred solution of the isomeric mixture of olefinic metathesis products (90.4 mg, 0.140 mmol) in anhydrous, degassed dichloromethane (2 mL) was charged with(1,5-cyclooctadiene)(pyridine)(tricyclohexylphosphine)-iridium(I)hexafluorophosphate (Crabtree's catalyst, 22 mg, 0.027 mmol) and stirred under an atmosphere of hydrogen at ambient temperature. After ca. 1.5 hours, an additional 1 mL of dichloromethane was added to the mixture, 20 h after the reaction was commenced, an additional 9 mg increment of Crabtree's catalyst was added to the solution. The reaction mixture was stirred for an additional 2 h before being concentrated in vacuo and purified by flash chromatography (12 g silica gel column eluted with a gradient of 0 to 40% [99:1 ethyl acetate:acetic acid] in hexanes) to provide the title compounds as a semi-solid white residue (54.6 mg, 34% overall combined yield, 60% material recovery for the hydrogenation).

Trifluoroacetic acid (600 μL, 7.84 mmol) was added to a stirred, room-temperature solution of an isomer mixture containing (S)-tert-butyl 6′-chloro-5-(((1S,2R)-2-((5-sulfamoylpentyl)thio)cyclobutyl)methyl)-3′,4,4′,5-tetrahydro-2H,2′H-spiro[benzo[b][1,4]oxazepine-3,1′-naphthalene]-7-carboxylate and a minor diastereomer (mixture obtained in Step 9, 17.3 mg, 0.027 mmol total) in dichloromethane (600 μL). After 2 h, the reaction mixture was concentrated in vacuo and three aliquots of anhydrous toluene were evaporated from the resulting residue to remove moisture from the crude carboxylic acid intermediates prior to macrocyclization. The crude intermediates exhibited the mass of the desired carboxylic acid intermediate by LC-MS, and this material was used in the macrocyclization reaction without further characterization.

A solution of N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (12 mg, 0.063 mmol) in anhydrous dichloromethane (1 mL) was added portionwise over the course of seven minutes to an ice-cold, stirred solution of the crude carboxylic acid intermediates generated above and N,N-dimethylpyridin-4-amine (6 mg, 0.049 mmol) in anhydrous dichloromethane (12 mL) under an atmosphere of dry nitrogen. The resulting stirred reaction mixture was allowed to gradually warm to rt and was aged for ca. 20 hours at this temperature, after which time it was partitioned between dichloromethane and 1 M aqueous hydrochloric acid. The organic layer was washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo to give a residue that was further purified by flash chromatography (4 g silica gel column eluted with a gradient of 0 to 25% [99:1 ethyl acetate:acetic acid) in hexanes] to provide the title compounds as a flaky white solid (8.9 mg, 56% overall combined yield). By comparison of NMR integrals and peak heights, the two isomers comprising the sample were present in a ratio of ca. 6:1. Co-integration of NMR signals for the major and minor species supported the assignment of the minor compound as a diastereomer, consistent with expectations based on the means of preparation, the known enantiomer ratio of the cyclobutane precursor described in Step 4, identical masses and retention times for both compounds observed by LC-MS and HPLC, respectively, and other considerations described in Step 7. 1H NMR (500 MHz, CD2Cl2) δ ppm 8.22 (br. s, 1H), 7.72 (d, J=8.6 Hz, 0.13H), 7.72 (d, J=8.6 Hz, 0.81H), 7.16-7.20 (m, 1H), 7.08-7.12 (m, 1.8H), 7.08 (apparent d, J=2.0 Hz, 0.07H), 7.04-7.07 (m, 1H), 6.95 (d, J=8.3 Hz, 0.86H), 6.95 (d, J=8.3 Hz, 0.14H), 4.23 (d, J=12.0 Hz, 0.16H), 4.08-4.14 (m, 1.84H), 3.81-3.91 (m, 2H), 3.72 (d, J=14.2 Hz, 1H), 3.34 (dt, J=14.8, 7.3 Hz, 1H), 3.21 (d, J=14.2 Hz, 1H), 3.01-3.11 (m, 2H), 2.74-2.79 (m, 2H), 2.57-2.67 (m, 1H), 2.49-2.55 (m, 2H), 2.01-2.12 (m, 4H), 1.78-1.96 (m, 3H), 1.56-1.76 (m, 7H), 1.39-1.47 (m, 1H). m/z (ESI, +ve ion) 575.0 (M+H)+, 597.1 (M+Na)+.

N-methylmorpholine oxide (30 mg, 0.256 mmol) was weighed into a flask containing an mixture of (1S,3′S,6R)-6-chloro-3,4-dihydro-2H,15′H-spiro[naphthalene-1,22′-[20]oxa[7,13]dithia[1,14]diazatetracyclo[14.7.2.03,6.019,24]pentacosa[16,18,24]trien]-15′-one 13′,13′-dioxide and a minor diastereomer (obtained in Step 10 of Example 195, 23.2 mg, 0.040 mmol total). A solution of osmium tetroxide (2.1 mg, 8.26 μmol) in 600 μL acetone was added followed by water (300 μL), and the resulting reaction mixture was vigorously stirred at ambient temperature for one hour. The oxidant was quenched by addition of 6 mL 1 M aqueous sodium thiosulfate and the crude product mixture was extracted into 1:5.7 isopropanol:dichloromethane. The aqueous layer was back-extracted 3× with 1:5.7 isopropanol:dichloromethane and the combined organics were washed with 1 M aqueous sodium thiosulfate that had been saturated in sodium chloride followed by brine, dried over magnesium sulfate, filtered and concentrated in vacuo to give a crude residue that was further purified by flash chromatography (4 g silica gel column eluted with a gradient of 30 to 100% [99:1 ethyl acetate:acetic acid] in hexanes) to provide a mixture of the title compounds as a flaky white solid (16.7 mg, 68% yield). Integration of aryl resonances in the proton NMR spectrum of this material showed it to be composed of a ca. 11:1 mixture of isomers containing the desired (3′S,6′R) diastereomer as the major compound along with a minor diastereomer inferred to arise from the minor enantiomer present in the cyclobutane starting material; however, as a purified sample of the minor compound was not obtained for exhaustive characterization, alternative structural assignments (as depicted above) for the minor diastereomer could not be definitively excluded.

STEP 1: (S)-TERT-BUTYL 4-HYDROXYHEXANOATE

The title compound was prepared in yields ranging from 49-51% from (S)-2-ethyloxirane and tert-butyl acetate by the method described in Journal of Organic Chemistry, 1989, 54, 2039.

STEP 2: (R)-TERT-BUTYL 4-(PYRIMIDIN-2-YLTHIO)HEXANOATE

Methanesulfonyl chloride (2.1 mL, 27.1 mmol) was added dropwise to a stirred, ice-cooled solution of (S)-tert-butyl 4-hydroxyhexanoate (4.729 g, 25.1 mmol, prepared in Step 1) and N-ethyl-N-isopropylpropan-2-amine (9.0 mL, 53.1 mmol) in anhydrous dichloromethane (125 mL) under an atmosphere of dry nitrogen. The resulting reaction mixture was allowed to gradually warm to ambient temperature and was aged overnight for a total of 17 h. The mixture was diluted in DCM, washed sequentially with ice-cooled 1 M aqueous hydrochloric acid, saturated aqueous sodium bicarbonate and brine, and then the combined organics were dried over magnesium sulfate, filtered and concentrated in vacuo to give the crude mesylate intermediate as a reddish-orange oil weighing 6.88 g.

Pyrimidine-2-thiol (3.24 g, 28.9 mmol) was suspended in degassed absolute ethanol (200 mL) under an argon atmosphere in a round-bottom flask equipped with a reflux condenser, and the resulting mixture was vigorously stirred at ambient temperature. Sodium ethoxide (21% w/w in ethanol, 10.00 ml, 26.8 mmol) was gradually added to the slurry, inducing dissolution of the thiol as its sodium salt. After 13 minutes, a solution of the crude mesylate intermediate generated above in degassed ethanol (50 mL) was added the mixture over the course of five minutes. The reaction mixture was heated at 60° C. in an oil bath for ca. 2 h. The reaction temperature was then increased to 100° C. and maintained at this temperature for one hour, after which solvents were removed in vacuo. The residue was taken back up into diethyl ether (100 mL) and washed sequentially with 1 M aqueous sodium hydroxide (2×) and brine. The organics were dried over magnesium sulfate, filtered and concentrated to give the crude product, which was further purified by flash chromatography (330 g silica gel column eluted with a gradient of 0 to 20% ethyl acetate in hexanes) to give the title compound as an orange oil (3.20 g, 45% yield).

STEP 3: (R)-N-METHOXY-N-METHYL-4-(PYRIMIDIN-2-YLTHIO)HEXANAMIDE

Trifluoroacetic acid (10 mL, 130 mmol) was added to a stirred, room-temperature solution of (R)-tert-butyl 4-(pyrimidin-2-ylthio)hexanoate (3.09 g, 10.9 mmol) in dichloromethane (10 mL). After 2 h, the reaction mixture was concentrated to give the crude carboxylic acid intermediate. Trace moisture and residual trifluoroacetic acid were liberated from this material by successive azeotropic co-distillations of anhydrous toluene (4×24 mL) from the reaction pot using a rotary evaporator, giving a pinkish-orange syrup that was redissolved in anhydrous dichloromethane (30 mL). The resulting stirred, solution was cooled to 0° C. in an ice-water bath under an atmosphere of dry nitrogen. Triethylamine (12.2 mL, 88 mmol), N,O-dimethylhydroxylamine hydrochloride (1.32 g, 13.53 mmol) and 1H-benzo[d][1,2,3]triazol-1-ol (2.24 g, 16.58 mmol) were added to the solution, followed by N1-((ethylimino)methylene)-N3,N3-dimethylpropane-1,3-diamine hydrochloride (EDCI, 3.18 g, 16.59 mmol). An aliquot of anhydrous dichloromethane (3 mL) was used to rinse all solid reactants of the joint of the flask into solution. The stirred mixture was allowed to gradually warm to ambient temperature. After ca. 13.5 hours, the reaction mixture was partitioned between dichloromethane and 15% (w/w) aqueous citric acid. The organics were sequentially washed with water, saturated aqueous sodium bicarbonate and brine, and were dried over magnesium sulfate, filtered and concentrated in vacuo. The resulting residue was further purified by flash chromatography (220 g silica gel column eluted with a gradient of 50 to 80% ethyl acetate in heptanes) to provide the title compound as a pale pink oil (2.66 g, 90% yield).

STEP 4: (R)-5-(PYRIMIDIN-2-YLTHIO)HEPTAN-2-ONE

Methylmagnesium bromide (3M in diethyl ether, 7.4 mL, 22.20 mmol) was added over the course of six minutes to a stirred, −45° C. solution of (R)-N-methoxy-N-methyl-4-(pyrimidin-2-ylthio)hexanamide (1.958 g, 7.27 mmol) in a mixture of anhydrous diethyl ether (33 ml) and anhydrous tetrahydrofuran (17 mL). After three hours, the reaction was quenched by cautious addition of saturated aqueous ammonium chloride (ca. 50 mL). The crude product was extracted into diethyl ether, washed with brine, dried over magnesium sulfate, filtered and concentrated in vacuo to provide a residue that was further purified by silica gel chromatography (eluent=5 to 40% ethyl acetate in heptanes) to give the title compound as a clear oil (968 mg, 54% yield).

N-butyllithium (2.5 M in hexanes, 295 μL, 0.738 mmol) was added dropwise over the course of four minutes to a stirred, −78° C. solution of diisopropylamine (108 μL, 0.770 mmol) in anhydrous diethyl ether (2.5 mL) under an atmosphere of dry nitrogen. Six minutes later, the solution was warmed to 0° C. and maintained at this temperature for 0.5 hours before being cooled again to −78° C. A solution of (R)-5-(pyrimidin-2-ylthio)heptan-2-one (157 mg, 0.700 mmol) in 1:1 diethyl ether:tetrahydrofuran (1 mL total) was added dropwise to the LDA solution over six minutes. The resulting ketone enolate solution was aged at −78° C. for ca. 1 hour, 45 minutes. A solution of (S)-methyl 6′-chloro-5-(((1R,2R)-2-formylcyclobutyl)methyl)-3′,4,4′,5-tetrahydro-2H,2′H-spiro[benzo[b][1,4]oxazepine-3,1′-naphthalene]-7-carboxylate (Intermediate AA11A, Step 20A, 160 mg, 0.352 mmol) in anhydrous tetrahydrofuran (1.2 mL total volume) was then added to the ketone enolate over the course of 0.5 hours. The mixture was aged for an additional 36 minutes at −78° C. and was then gradually cannulated while at this temperature into a vigorously stirred suspension of crushed ice (ca. 50 mL) in 0.5 M pH 7 phosphate buffer (25 mL).

The ketone (60 mg, 0.070 mmol, Step 1) was dissolved in MeOH (2.0 mL) and cooled to 0° C. Sodium borohydride (26 mg, 0.70 mmol) was then added and the mixture was allowed to stir for 30 minutes. The reaction went from a clear solution to forming a white precipitate upon completion. The mixture was then quenched with saturated sodium bicarbonate solution and concentrated under reduced pressure and then extracted between organic (EtOAc, DCM, DCM/MeOH) and water (15 mL). It was noted that a white precipitate was never solubilized throughout the workup and was saved. The combined organic layers were dried over magnesium sulfate and concentrated. The material was purified by Preparative LC, but low recovery was observed.

STEP 1: (1R,2S)-2-ALLYLCYCLOPENTANOL AND (1S,2R)-2-ALLYLCYCLOPENTANOL

To allylmagnesium bromide, 1.0 M solution in diethyl ether (100 mL, 100 mmol) stirred at −10 to −18° C. in a 500-mL single-necked round-bottomed flask was added slowly 1,2-epoxycyclopentane (4.12 mL, 47.6 mmol) through a syringe over a period of 30 min. The resulting mixture was stirred at this temperature and allowed to slowly warm up to rt and stirred at rt overnight (18 h). The reaction mixture was thoroughly cooled in an ice bath before slowly and very carefully quenched with ice cold saturated ammonium chloride aqueous solution. Strong gas evolution was observed. Some chunky and gummy precipitate formed at the bottom of the flask. This mixture was further diluted with ether and ice cold ammonium chloride aqueous solution. It was stirred and occasionally sonicated to give a clear two-phase mixture. The layers were separated and the aqueous phase was extracted with ether (2×). The combined organics were combined and washed with saturated ammonium chloride aqueous solution (1×), dried over anhydrous sodium sulfate, and concentrated in vacuo to give a racemic mixture of (1R,2S)-2-allylcyclopentanol and (1S,2R)-2-allylcyclopentanol (6.6 g, 52.3 mmol, 110% yield) as a colorless oil.

STEP 2: (1S,2R)-2-ALLYLCYCLOPENTYL METHANESULFONATE AND (1R,2S)-2-ALLYLCYCLOPENTYL METHANESULFONATE

To a stirred ice-cooled solution of a racemic mixture of (1S,2R)-2-allylcyclopentanol and (1S,2R)-2-allylcyclopentanol (3.0 g, 23.77 mmol) and triethylamine (7.27 mL, 52.3 mmol) in DCM (50 mL) was slowly added methanesulfonyl chloride (2.82 mL, 35.7 mmol) through a syringe. The resulting mixture was stirred at 0° C. for a period of 1 h. The crude mixture was poured into ice and 1 N aqueous HCl solution and extracted with DCM (2×). The combined organics were once again washed with 1 N aqueous HCl solution followed by brine (2×) and dried over anhydrous sodium sulfate. The residue after concentration invacuo gave a racemic mixture of (1S,2R)-2-allylcyclopentyl methanesulfonate and (1R,2S)-2-allylcyclopentyl methanesulfonate (5.0 g, 24.48 mmol, 103% yield) as a nearly colorless oil, directly taken onto the next step.

STEP 3: 2-(((1R,2R)-2-ALLYLCYCLOPENTYL)THIO)PYRIMIDINE AND 2-(((1S,2S)-2-ALLYLCYCLOPENTYL)THIO)PYRIMIDINE

To a stirred mixture of 2-mercapto-pyrimidine (3.64 g, 32.5 mmol) and potassium carbonate anhydrous (5.52 g, 39.9 mmol) in DMF (20 mL) was added at rt a solution of a racemic mixture of (1S,2R)-2-allylcyclopentyl methanesulfonate and (1R,2S)-2-allylcyclopentyl methanesulfonate (5.1 g, 24.96 mmol) in DMF (20 mL). The resulting mixture was stirred at rt for a period of 17 h. Within the first 1.5 h or so, the reaction mixture got so creamy that the stirring became nearly ineffective. More DMF (3×10 mL) was added and the mixture was stirred at rt overnight. It's observed next morning the stirring had been disabled due to the fact that the mixture became a very thick paste. The crude mixture was poured into ice and saturated sodium bicarbonate aqueous solution and extracted with ether (3×). The combined organics were washed with water (1×) followed by brine (1×), dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue was subjected to combi-flash column chromatography (EtOAc/hexanes, 20 min at 10%, 80 g ISCO silica gel column) to give 4.3 g of an impure racemic mixture of 2-(((1R,2R)-2-allylcyclopentyl)thio)pyrimidine and 2-(((1S,2S)-2-allylcyclopentyl)thio)pyrimidine, directly taken onto the next step.

STEP 4: 2-(((1R,2R)-2-ALLYLCYCLOPENTYL)SULFONYL)PYRIMIDINE AND 2-(((1S,2S)-2-ALLYLCYCLOPENTYL)SULFONYL)PYRIMIDINE

To a stirred ice-cooled solution of the above impure racemic mixture of 2-(((1R,2R)-2-allylcyclopentyl)thio)pyrimidine and 2-(((1S,2S)-2-allylcyclopentyl)thio)pyrimidine (2.1 g, 9.53 mmol) in DCM (30 mL) was added 3-chlorobenzoperoxoic acid (3.45 g, 20.02 mmol) in two portion over a period of 10 min. The resulting mixture was stirred at 0° C. for about 2 h. (Note that there was a major peak on LC-MS which gave rise a mass consistent with the intermediate sulfoxide. So the reaction was allowed to go for a much extended duration) The reaction mixture appeared a white heterogeneous paste. DMF (1.0 mL) was added and the reaction mixture became a clear solution. And it was stirred at rt for 2.5 h. The reaction mixture was then poured into ice and saturated sodium bicarbonated aqueous solution and extracted with DCM (3×). The combined organics were washed with ice-cold sodium bicarbonate aqueous solution (1×) followed by brine (1×), dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue was subjected to combi-flash column chromatography (EtOAc/hexanes, 35 min from 0 to 100% and 10 min at 100%, 40 g ISCO silica gel column) to give 1.05 g of a racemic mixture of 2(((1R,2R)-2-allylcyclopentyl)sulfonyl)pyrimidine and 2-(((1S,2S)-2-allylcyclopentyl)sulfonyl)pyrimidine as a colorless oil.

The resulting mixture was stirred at rt for 75 min. The LC-MS indicated the complete consumption of the sm. Amidoperoxymonosulfuric acid (1.436 g, 12.70 mmol) was added at rt in one portion as a solid followed by water (18 mL). The resulting mixture was stirred at rt for 2 min and at 90° C. in a preheated oil bath for 5 min and at rt for 1 h 45 min. The mixture was poured into ice and 1 N sodium hydroxide aqueous solution and extracted with EtOAc (3×). The combined organics were dried over anhydrous sodium sulfate and concentrated in vacuo to give an impure mixture of the title compounds with the major contaminant being 2-methoxypyrimidine, directly taken onto the next step.

The flask was subjected to 3 cycles of evacuation and back-filling with nitrogen before DCE (2.1 mL) was introduced via syringe under argon at rt. To this stirred solution was added via a syringe a solution of 2nd generation hoveyda-grubbs catalyst (10.44 mg, 0.017 mmol) in DCE (1.2 mL) at rt under argon. The resulting mixture was stirred at rt under argon for a period of 1 h 45 min.

The combined organics were washed once again with 1 N aqueous HCl solution followed by brine (2×) and dried over anhydrous sodium sulfate. Concentration in vacuo gave a racemic mixture of (1S,2S)-2-allylcyclopentyl methanesulfonate and (1R,2R)-2-allylcyclopentyl methanesulfonate (3.83 g, 18.75 mmol, 103% yield) as a nearly colorless oil, taken onto the step.

STEP 4: 2-(((1R,2S)-2-ALLYLCYCLOPENTYL)THIO)PYRIMIDINE AND 2-(((1S,2R)-2-ALLYLCYCLOPENTYL)THIO)PYRIMIDINE

A mixture of 2-mercapto-pyrimidine (3.15 g, 28.1 mmol) and potassium carbonate anhydrous (4.4 g, 31.9 mmol) in DMF (40 mL) was stirred at rt for 10 min before a solution of a mixture racemic mixture of (1S,2S)-2-allylcyclopentyl methanesulfonate and (1R,2R)-2-allylcyclopentyl methanesulfonate (3.83 g, 18.75 mmol) in THF (40.0 mL) was added at rt. The resulting mixture was stirred at rt for 10 min and at 70° C. for a period of 16 h. The crude mixture was poured into ice and saturated sodium carbonate aqueous solution and extracted with EtOAc (3×). The combined organics were washed with saturated sodium carbonate aqueous solution (1×) followed by water (1×), dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue was subjected to combi-flash column chromatography (EtOAc/hexanes, 5 min at 0% and 25 min from 0 to 30%, 80 g ISCO silica gel column) to give a racemic mixture of 2-(((1R,2S)-2-allylcyclopentyl)thio)pyrimidine and 2-(((1S,2R)-2-allylcyclopentyl)thio)pyrimidine (1.92 g, 8.71 mmol, 46.5% yield) as a colorless oil, taken onto the next step.

STEP 5: 2-(((1R,2S)-2-ALLYLCYCLOPENTYL)SULFONYL)PYRIMIDINE AND 2-(((1S,2R)-2-ALLYLCYCLOPENTYL)SULFONYL)PYRIMIDINE

To a stirred ice-cooled solution of a racemic mixture of 2-(((1R,2S)-2-allylcyclopentyl)thio)pyrimidine and 2-(((1S,2R)-2-allylcyclopentyl)thio)pyrimidine (0.87 g, 3.95 mmol) in DCM (20 mL) and DMF (2.00 mL) was added 3-chlorobenzoperoxoic acid (1.858 g, 8.29 mmol) in 3 portions as a solid over 10 min. The resulting mixture was stirred at 0° C. for about 1 h 15 min. The ice bath was then removed and the mixture was stirred at rt for 2 h. The reaction was then poured into ice and saturated sodium carbonate aqueous solution and extracted with DCM (3×). The combined organics were washed with ice-cold sodium carbonate aqueous solution (1×), dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue was subjected to combi-flash column chromatography (EtOAc/Hexanes, 25 min from 0 to 100%, 24 g ISCO silica gel column) to give a racemic mixture of 2-(((1R,2S)-2-allylcyclopentyl)sulfonyl)pyrimidine and 2-(((1S,2R)-2-allylcyclopentyl)sulfonyl)pyrimidine (0.90 g, 3.57 mmol, 90% yield) as a colorless oil, taken onto the next step.

STEP 6: (1R,2S)-2-ALLYLCYCLOPENTANE-1-SULFONAMIDE AND (1S,2R)-2-ALLYLCYCLOPENTANE-1-SULFONAMIDE

The 1st step: To a stirred solution of a racemic mixture of 2-(((1R,2S)-2-allylcyclopentyl)sulfonyl)pyrimidine and 2-(((1S,2R)-2-allylcyclopentyl)sulfonyl)pyrimidine (0.90 g, 3.57 mmol) in MeOH (35 mL) was added at rt sodium methoxide, 25 wt % solution in methanol (0.795 mL, 3.57 mmol) via a syringe. The resulting mixture was stirred at rt for 25 min and on rotavap at 52° C. for 10 min to remove the volatiles. The residue was subjected to high vacuum.

The 2nd step: To the above residue was added water (30 mL) followed by sodium acetate trihydrate (0.67 mL, 7.13 mmol) and amidoperoxymonosulfuric acid (0.81 g, 7.13 mmol) at rt. The resulting clear solution was stirred at 50° C. in a preheated oil bath for a period of 40 min. The LC-MS showed this time that the desired product was the minor while still the intermediate sulfinate was the overwhelmingly major. The temperature was raised to 95° C. and the reaction mixture was stirred at this temperature for 10 min. The LC-MS showed this time that the desired product became the major with some of the intermediate sulfinate still remaining. The reaction was put back into the 95° C. oil bath and stirred for 10 min. The LC-MS showed the reaction stalled with some of the fulminate still remaining. After briefly cooled, one equivalent each of sodium acetate and amidoperoxymonosulfuric acid was added. The mixture was stirred at 95° C. for 10 min and became cloudy upon cooling. It was basified using ice cold saturated sodium carbonate and extracted with 20% i-PrOH/DCM (5×). The combined organics were dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was subjected to combi-flash column chromatography (EtOAc/Hexanes, 20 min from 0 to 70%, 24 g ISCO silica gel column) to give, as a colorless crystalline solid, 0.61 g of a mixture of the title compound and 2-methoxypyrimidine (the by-product) in a ratio of 3.5 to 1.

The flask was subjected to 3 cycles of evacuation and back-filling with nitrogen before DCE (5 mL) was introduced through a syringe under nitrogen. The resulting mixture was stirred under nitrogen at rt for a period of 4 h. The crude mixture was loaded onto a silica gel precolumn and subjected to combi-flash column chromatography ((10% MeOH/DCM with 0.3% AcOH)/DCM), 25 min from 0 to 100%, 24 g ISCO silica gel column) to give a mixture of the title compounds (0.19 g, 0.302 mmol, 79% yield) as a gray solid, taken onto the next step.

The resulting mixture was stirred at 0° C. for about 1 h. DMF (1.2 mL) was added to attain complete dissolution and the mixture was further stirred at 0° C. for 45 min. Note that the reaction was closely monitored by LC-MS and went through a few rounds of adding more m-CPBA as follows. More m-CPBA (0.6 g) was added at 0° C. and the mixture was stirred at this temperature for 20 min before the ice bath was removed. It was stirred at rt for 20 min. The mixture was cooled again in an ice bath and more m-CPBA (0.55 g) was added and the mixture was stirred at 0° C. for 1 h. Again, more m-CPBA (0.26 g) was added at 0° C. and the mixture was stirred at this temperature for 1 h. The reaction mixture was then poured into ice and saturated sodium bicarbonate aqueous solution and extracted with DCM (3×). The combined organics were washed with ice cold sodium bicarbonate aqueous solution (1×), dried over anhydrous sodium sulfate, and concentrated in vacuo. The residue was subjected to combi-flash column chromatography ((10% MeOH/DCM)/DCM, 35 min from 0 to 60%, 40 g ISCO silica gel column) to give a racemic mixture of 1-((3R,4S)-3-allyl-4-(pyrimidin-2-ylsulfonyl)pyrrolidin-1-yl)ethanone and 1-((3S,4R)-3-allyl-4-(pyrimidin-2-ylsulfonyl)pyrrolidin-1-yl)ethanone (0.436 g, 1.476 mmol, 72.0% yield) as a colorless film, taken onto the next step.

BIOLOGICAL ASSAYS

Cell Free Mcl-1:Bim Affinity Assay (Mcl-1 HTRF)

The inhibition of the Mcl-1/Bim interaction was measured using a time-resolved fluorescence resonance energy transfer (TR-FRET) assay. The recombinant human Mcl-1 (C-terminally 6×His tagged Mcl-1 containing residues 171-327) was generated at Amgen Inc (Thousand Oaks, Calif.). A biotinylated peptide derived from human Bim (residues 51-76) was purchased from CPC Scientific (San Jose, Calif.). The TR-FRET assay was conducted in a 384-well white OptiPlate™ (PerkinElmer, Waltham, Mass.) in a total volume of 40 μL. The reaction mixture contained 0.1 nM Mcl-1(171-327), 0.05 nM biotin-Bim(51-76), 0.05 nM LANCE® Eu-W1024 Anti-6×His (PerkinElmer), 0.072 nM Streptavidin-XLent (Cisbio, Bedford, Mass.), and serially diluted test compounds in the binding buffer of 20 mM Hepes, pH 7.5, 150 mM NaCl, 0.016 mM Brij®35, and 1 mM dithiothreitol. Test compounds were pre-incubated with Mcl-1(171-327) and biotin-Bim (51-76) for 60 min before addition of the detection mixture (LANCE® Eu-W1024 Anti-6×His and Streptavidin-XLent). The reaction plates were further incubated overnight and then were read on an Envision® multimode reader (PerkinElmer). Fluorescence signals were measured at 620 nm (40-nm bandwidth) and 665 nm (7.5-nm bandwidth) with a 60 μs delay after excitation at 320 nm (75-nm bandwidth). The signal ratio at 665/620 nm corresponded to the Mcl-1/Bim interaction and was used in all data analyses. The IC50 values of test compounds were determined from duplicate data by analyzing competition curves using a four-parameter sigmoidal model in GraphPad Prism (GraphPad Software, San Diego, Calif.) or in Genedata Screener® (Genedata, Basel, Switzerland).

Cell Viability Assay (OPM-2 10 FBS)

The human multiple myeloma cell line, OPM-2, was cultured in complete growth medium containing RPMI 1640 and 10% fetal bovine serum (FBS). Cells were seeded into 384-well plates at 3000 cells/well density in complete growth medium containing 10% FBS, and incubated for 16 h with serially diluted test compounds in a 37° C. incubator with 5% CO2. Cell viability was tested using CellTiter-Glo® assay (Promega, Madison, Wis.) according to the manufacturer recommendations. Luminescence was determined using an EnVisio® Multilabel plate reader 25 min after the addition of detection reagent. IC50 values were then calculated with Xlfit using a logistical 4-parameter fit model in GraphPad Prism (GraphPad Software, San Diego, Calif.) or in Genedata Screener® (Genedata, Basel, Switzerland).
